Ansys Workbench Setup for Heat Distribution Analysis

Here's some guidance for your setup in Ansys Workbench:

Solver:

For this heat transfer problem involving conduction only, you should use the Steady-State Thermal solver within Ansys Workbench. This solver focuses on situations where the temperature doesn't change with time.

Boundary Conditions:

Troubleshooting Patchy Water Film in Discrete Phase Model (DPM) Coupled with Eulerian Wall Film (EWF) CFD

 There are a few possible reasons why  cloud map might be showing a granular distribution for the water film thickness when using a coupled DPM-EWF model:

1. Particle Size Discretization: In the DPM, you likely define a range of particle sizes to represent the water droplets. This discretization can lead to a blocky or granular appearance in the cloud map, especially if the range is large or the number of size classes is small.

2. Limited Resolution: Cloud maps often have a limited number of cells to represent the solution space. If the water film is thin or the cloud map resolution is coarse, you might see a patchy or granular distribution instead of a smooth film.

3. Turbulent Fluctuations: If you're simulating a turbulent flow, the water film thickness may fluctuate due to the turbulent eddies. These fluctuations can be captured by the DPM and reflected as a granular distribution in the cloud map.

chtMultiRegionTwoPhaseEulerFoam Stops at Constructing Face Momentum Equations

Why does chtMultiRegionTwoPhaseEulerFoam halt at "Constructing face momentum equations" without errors?

The fact that chtMultiRegionTwoPhaseEulerFoam stops at the "Constructing face momentum equations" stage without any error message suggests an issue with the initial conditions or case setup. Here are some potential causes to investigate:

Troubleshooting Pressure Field and Continuity Errors in intermixingFoam Simulations

Question: How to fix pressure field issues and continuity errors in an intermixingFoam simulation for simulating two mixing fluids in a rocket engine chamber?

I'd be glad to assist you with the pressure field and continuity errors you're encountering in your intermixingFoam simulation.

Troubleshooting buoyantFoam Crashes in Mixed Convection Simulations

What are some potential solutions to address buoyantFoam crashes during mixed convection simulations in OpenFOAM?

I'd be glad to help you with the buoyantFoam crashes you're encountering in mixed convection simulations or when using higher-order schemes.

Gmsh Error: Nodes Not on Z=0 Plane for Plane Stress/Strain Analysis

 The error message you're encountering in Gmsh indicates that the nodes in your STL file are not located on the z=0 plane, which is a requirement for elements representing plane stress, plane strain, or axisymmetric conditions.

Here are two possible solutions to address this issue:

ICEM Meshing Error: "Too Many Nested Evaluations (Infinite Loop?)"

This error message in ICEM, encountered while linking block edges to a geometric curve, indicates a potential issue with the way you're defining the link. Here are some possible causes and solutions:

Causes:

• Circular Dependency: The linking process might be creating a circular dependency between the edges and the curve. This could happen if the definition of the link relies on information derived from the linked entities themselves.
• Incorrect Selection: You might be inadvertently selecting multiple edges or curves during the linking process, creating a loop.
• Software Bug (Less Likely): While less common, there's a slight chance this error could be caused by a bug in the specific version of ICEM you're using (Ansys 2019 R1).
