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 geometry ¹. It is developed by Sandia National Laboratories and the University of New Mexico ². 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:
- Intel GPU driver
- [AMD GPU driver]
- [NVIDIA GPU driver]
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 website ¹ or from this PDF document ². Here are the main steps:

Download the latest version of FreeFEM for Windows from the official page ³. 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 here ⁴, 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 page ¹. 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 document ² or the official website ³ to install and run Calculix for Windows.
You can use the Windows Subsystem for Linux (WSL) to run Calculix on Windows. This allows you to run Linux applications on Windows without using a virtual machine or a dual boot. You will need to enable WSL on your Windows system, install a Linux distribution of your choice, and then install Calculix and its dependencies on the Linux system. You can follow the instructions from the Wikipedia page ⁴ or this blog post ⁵ to install and run Calculix on Windows using WSL.
You can use a virtual machine or a dual boot to run Calculix on Windows. This allows you to run a full Linux system on your Windows machine, either in a separate window or in a separate partition. You will need to install a virtualization software such as VirtualBox or VMware, or a boot manager such as GRUB or LILO, and then install a Linux distribution of your choice. You can then install Calculix and its dependencies on the Linux system. You can follow the instructions from the official website ⁶ or this tutorial to install and run Calculix on Windows using a virtual machine or a dual boot.
