Heat Transfer Problem in Ansys

AI Thread Summary
Users are experiencing issues with Ansys 16.2 during a Transient Thermal Analysis, specifically encountering an error related to starting the solver module. Despite increasing virtual memory as suggested in the Ansys Mechanical User Guide, the problem persists. Participants are advised to check their system specifications, including RAM and operating system type, as well as to consider simplifying their models by reducing mesh size or using symmetry to decrease computational demands. Suggestions include creating a smaller mesh to identify the threshold for successful simulation. Overall, memory limitations appear to be a common concern in resolving these simulation errors.

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 errorAn 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%20Mechanical%20Users%20Guide.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 gratefulWith 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.
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
