Hello, I tried to restart an analysis from a Coupled-Temperature-Displacement analysis which is terminated due to time limit. The original and restart job was performed on a cluster. Whenever I tried to restart I would get the following error message (I don't think it comes from Abaqus):

Traceback (most recent call last):

File "SMAPylModules/SMAPylDriverPy.m/src/analysis.py", line 1744, in 

File "SMAPylModules/SMAPylDriverPy.m/src/analysis.py", line 1231, in run

File "SMAPylModules/SMAPylDriverPy.m/src/symbolicConstants.py", line 92, in __new__

ValueError: SymbolicConstant name '' may only contain upper case, digit or underscore

The installation is in linux x64. In fact, I tried a test case with a single element with Static analysis as well as importing the model from restart file, and the error still occurred. I suspect there is an error in the "odb" file. However, the "odb" can be viewed in A/CAE. In addition, if I copy the original model file from the original input, then create a restart job inside CAE, the restart job can run without error. 

I tried and exact same input on another server with single CPU and linux system, and the restart worked normally. I also tried the same restart input on a Windows machine and it also worked. I wonder if this is an issue with ABAQUS installation but I cannot locate the verification job files so I cannot run ABAQUS verify. 

Any tips or suggestions will be highly appreciated!
