Hi,

I am getting the message "An error occurred while starting the solver module. Please refer to the Troubleshooting section in the ANSYS Mechanical User Guide for more information" whenever I try to solve any type of Thermal or Mechanical analysis. I already have read all the posts I could find and nothing helped.

It happens for all the ANSYS projects that I created a year ago using v18 (can't remember exactly which one). My laptop is a Windows 10, 64-bit system and I have plenty of Hard drive space and RAM memory and administrative privileges. I even performed a "soft-reset" and installed version Academic Student 2019 R1 - neither my previous projects or new ones work.

 Can anyone help, please? Thanks

 

Luis

Additional facts:

• When I open the solver directory, there is no Solver.out file.


• All the folders have only English characters, as well as my user and computer IDs


• Renaming the C:UsersluisdAppDataRoamingAnsys v193 file to v193.old did not work.


•  I checked the name references for the loads and boundary conditions and none of them were modified from one release to another.


• I managed to use FLUENT, though, but I can't open it from the workbench window and have to use the CMD:

                             cd C:Program FilesANSYS IncANSYS Studentv193fluentntbinwin64

 

                             fluent ^-r19.3.0 2ddp -meshing -tm8 -t8

Honestly, I never tried opening Mechanical APDL before.

•  I managed to solve one of the static structural simulations I made, using Mechanical APDL (thanks to tsiriaks for his advice). However, when reading the results for a transient thermal simulation in Workbench, I get the error

 Your product license has numerical problem size limits, you have exceeded these problem size limits and the solver cannot proceed.

 

• I checked the license status from Mechanical APDL and I got this

 

ANSYS Licensing Interconnect path is empty.

 

Please see the Troubleshooting Section in the ANSYS Licensing Guide for more details.

But I made these simulations with the same type of Ansys Academic license originally, and everything used to solve without problems.

For your original issue, that happened with ANSYS Mechanical (in Workbench) , right ? not Mechanical APDL  What if you create a brand-new, test static structural project, does this encounter the same issue ? Please post the screenshot of the all relevant errors.

For the issue with size limit, see this (this is for ANSYS Mechanical but may give some idea for Mechanical APDL)

Hi,

Please find the screenshot of the error here below. It happens for any simulation I try to solve with Ansys Mechanical. I've tried Thermal, Structural, Eigenvalue, and always get the same result.

 

 

[tsiriaks]

From your Mechanical GUI above, click Tools -> Write Input File , then save it somewhere.

Open M-APDL Launcher, specify 'ANSYS Batch' in Simulation Environment and specify the path and file name of your Input File, change Working Directory to C:Temp, then click Run. Post any error that comes up from this.
