How do I install GOMA on Windows?

GOMA is a parallel and scalable multiphysics software package for modeling and simulation of real-life physical processes, with a basis in computational fluid dynamics for problems with evolving geometry1. It is developed by Sandia National Laboratories and the University of New Mexico2. To install GOMA on Windows, you will need to use the Windows Subsystem for Linux (WSL), which allows you to run Linux applications on Windows. Here are the steps to install GOMA on Windows using WSL:

  • First, you need to enable WSL on your Windows system. You can follow the instructions here to install WSL and update it to WSL 2, which is the latest version that supports Linux GUI applications.

  • Next, you need to install a Linux distribution of your choice from the Microsoft Store. For this tutorial, we will use Ubuntu 20.04, which is one of the supported distributions for GOMA. You can find Ubuntu 20.04 here and install it on your system.

  • After installing Ubuntu 20.04, you need to launch it and set up your username and password. Then, you need to update and upgrade your system by running the following commands in the Ubuntu terminal:

    sudo apt update
sudo apt upgrade

  • Next, you need to install an X server for Windows, such as VcXsrv, which will allow you to run Linux GUI applications on Windows. You can download VcXsrv from here and install it on your system. Make sure you let it through your firewall and disable access control.

  • Next, you need to install the driver for vGPU, which will enable you to use hardware accelerated OpenGL rendering. You can find the driver matching your system from the links below:

  • Next, you need to enable systemd on WSL, which is required for running GOMA. You can use the script from [here] to enable systemd on WSL. To use the script, run the following commands in the Ubuntu terminal:

    git clone https://github.com/DamionGans/ubuntu-wsl2-systemd-script.git
cd ubuntu-wsl2-systemd-script/
bash ubuntu-wsl2-systemd-script.sh

  • Next, you need to shut down WSL by running the following command in the Windows PowerShell:

    wsl --shutdown

  • Next, you need to download and install GOMA on WSL. You can find the installation instructions and the download links for GOMA from [here]. Follow the steps to install GOMA and its dependencies on WSL.

  • Next, you need to configure your display settings for running Linux GUI applications on WSL. To do this, open your ~/.bashrc file in the Ubuntu terminal by running:

    nano ~/.bashrc

    And paste the following lines at the end of the file and save it:

    export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2}'):0
export LIBGL_ALWAYS_INDIRECT=1

  • Finally, you can run GOMA on WSL by launching your X server on Windows and then running the following command in the Ubuntu terminal:

    goma

    You should see the GOMA GUI window on your Windows desktop. You can now use GOMA to model and simulate various physical processes.

How do I install FreeFEM on Windows?

To install FreeFEM on Windows, you can follow the instructions from the official website1 or from this PDF document2. Here are the main steps:

  • Download the latest version of FreeFEM for Windows from the official page3. Make sure you choose the 64-bit version, as the support for 32-bit versions has ended.

  • Install the software without changing the installation path. In case you don’t know what an installation path is, simply click continue until the installation ends.

  • Install MSMPI for parallel version under Windows 64. You can download MS MPI V10.1.2 from here4, and install both msmpisdk.msi and MSMpiSetup.exe. Make sure you let it through your firewall and disable access control.

  • You should have two new icons on your desktop: FreeFem++ (VERSION).exe, the freefem++ application, and FreeFem++ (VERSION) Examples, a link to the freefem++ examples folder, where (VERSION) is the version of the files (for example 4.6).

  • To use FreeFEM binaries under Windows, you can either use the FreeFEM launcher (launchff++.exe) or use a shell terminal (cmd, powershell, bash, etc.). To launch the sequential version, you can run:

    C:\>"Program Files (x86)\FreeFem++\FreeFem++.exe" <mySequentialScript.edp>

    To launch the parallel version, you can run:

    C:\>"Program Files\Microsoft MPI\Bin\mpiexec.exe" -n <nbProcs> C:\>"Program Files (x86)\FreeFem++\FreeFem++-mpi.exe" <myParallelScript.edp>

How to install Calculix on Windows?

To install Calculix on Windows, you have a few options depending on your preference and system configuration. Here are some of them:

  • You can download and install Calculix for Windows from the SourceForge page1. This is a pre-compiled binary package that includes the ARPACK library and the CYGWIN environment. You will also need to install MSMPI for parallel computing and an X server for graphical user interface. You can follow the instructions from the PDF document2 or the official website3 to install and run Calculix for Windows.

How to... fix "gui-domain-label: no domain selected" in Ansys Fluent and MEMERR in CFX

In today's post, we will deal with another error that may occur during the analysis. The error that is described below concerns Fluent and the wrong definition of user monitors that are displayed during simulation. These can be monitors concerning the average velocity in the domain volume, the values of the maximum temperatures of the solid domains, the average values of the heat transfer coefficient from the defined planes of the model, etc. Generally speaking, today's entry is about how to correctly define monitors and how to transfer them between subsequent analyzes. Example of "gui-domain-label" error in Fluent

How to define Joint in Ansys Static Structural and examples to use

  Joint boundary condition is a type of connection element that allows you to model the relative motion and interaction between two or more bodies in a structural analysis. Joint boundary condition can be used to simulate various types of joints, such as revolute, cylindrical, spherical, planar, slot, universal, and fixed joints. Joint boundary condition can also be used to apply loads and moments to the connected bodies. To use joint boundary condition in Ansys Static Structural, you need to follow these steps: In the Model tree, right-click Connections and select Insert > Joint. In the Details view, select the type of joint you want to create from the drop-down list. In the Geometry section, select the two or more bodies that you want to connect with the joint. You can also specify the location and orientation of the joint coordinate system (JCS) using the options available. In the Definition section, specify the degrees of freedom (DOF) that you want to allow or restrict for the

Types of contacts on Ansys Static Structural and examples to use

Ansys Static Structural is a software that allows you to perform linear and nonlinear static analysis of structures, such as beams, plates, shells, and solids. One of the important aspects of static structural analysis is the contact between different parts of the structure, which can affect the stress, deformation, and load transfer. According to the web search results, there are three main types of contacts in Ansys Static Structural: bonded, frictionless, and frictional¹². Each type of contact has different characteristics and applications, depending on the behavior of the interface between the parts. - Bonded contact: This type of contact assumes that the parts are perfectly attached to each other, and there is no relative motion or separation between them. This means that both the normal and tangential forces are very large and resist any external forces that try to break or slide the parts. Bonded contact is useful for modeling welded joints, adhesive contacts, or some bolted con
