Heat Transfer Problem in Ansys

  • #1
Dear All,

I am facing a problem in Ansys

Ansys issue.

I am solving a model (Transient Thermal Analysis (Heat Flow from Hydrothermal Vessel)) in Ansys 16.2 Workbench

While reaching modeling stage, and upon running the simulation, program gives an below error


An error occurred while starting the solver module. Please refer to the Troubleshooting section in the ANSYS Mechanical User Guide.
Project>Model>Transient Thermal>Solution

The solution of which is referred to at, and is mentioned in
Ansys Mechanical User Guide (http://148.204.81.206/Ansys/150/ANSYS Mechanical Users Guide.pdf) under the heading of

"An Error Occurred While Starting the Solver Module" (Page 1419)

According to which, I must access Control Panel of my computer to increase my virtual memory to run this simulation.

Even after doing that, problem persists.

What should I do?

I shall be extremely grateful


With regards,
Ali

How many nodes and elements in your model, and how much RAM and hard disk space does your computer have? Is it a 32-bit or 64-bit operating system?

Also, what kind of boundary conditions are you using in the model? Have you considered making an axi-symmetric or quarter-symmetry model to reduce the hardware requirements?

Respected Sir,
I face the same problem now?
Have you solved it?
If yes, how did you solve it?

Thanks in advance.

Hello expert,
I have a similar problem as M.M Ali Rafique.
I have nearing 10lakhs nodes.
My system RAM is 8GB and 1TB hard disk and no HDD.
It is a 64 bit OS. All the heat convection and radiation is considered in my case.
Complex geometry are removed for analysis.

Please give me a solid solution.

Thanks in advance

You might not have enough memory to run this case. Try creating a smaller mesh (like 2 times smaller) to see if it runs, reduce your mesh until it starts.
