Bug located in Mapdl.input() while executing "solve"

Description of the bug

Pymapdl cannot complete ansys.input('analysis','inp') due to the SOLVE command being issued as an APDL command and not a pymapdl command. The analysis.inp file issues material properties, boundary conditions, and executes back-to-back analyses, but hangs up when the solve command is embedded. If I use convert_script so that the solve is completed by ansys.solve(), the analysis can be completed. With the attached input file, it's resulting in additional issues for the modal analysis solve (Cannot complete MODOPT or SOLVE)

Truncated error when solve is in the analysis.inp file

AAS_CORBA.MAPDL.Exceptions.EAnsysUnknown: AAS_CORBA.MAPDL.Exceptions.EAnsysUnknown(code=1, 
description='RunCommandStr is not allowed during distributed solve.', scope='MAPDL', interfaceName='ICoMapdlUnit', 
operation='executeCommand', moreInfo='/GO')

Truncated error after issueing convert script, then running solve through the end of the inp file in pymapdl

AAS_CORBA.MAPDL.Exceptions.EAnsysUnknown: AAS_CORBA.MAPDL.Exceptions.EAnsysUnknown(code=-15, 
description='Low-level communication error -15: Connection was closed', scope='MAPDL', interfaceName='ICoMapdlUnit', 
operation='executeCommand', moreInfo='SOLVE,')

Currently using ANSYS 2020 R1 on Windows

Steps To Reproduce

Convert input file for the analysis (attached) to analysis.inp. It is the input file for ANSYS Verification Manual 274. analysis.txt
Run these commands -- option to omit ansys.non_interactive as problem persists with and without this mode toggled
```
from ansys.mapdl.core import launch_mapdl
```

path = './Test/VMsubtest' ansys = launch_mapdl(run_location=path,override=True,allow_ignore=True,log_apdl=path+'/pymapdl_htc_log.txt')
with ansys.non_interactive: ansys.input('analysis','inp') ansys.finish() ansys.exit()

OR
```py
from ansys.mapdl.core import launch_mapdl

path = './Test/VMsubtest'
ansys = launch_mapdl(run_location=path,override=True,allow_ignore=True,log_apdl=path+'/pymapdl_htc_log.txt')    
ansys.input('analysis','inp')
ansys.finish()
ansys.exit()

akaszynski commented 2 years ago

It looks like it's still using an older version of MAPDL and the (less that optional) CORBA mode. Can you use v222 and the gRPC mode?

emhen commented 2 years ago

Switched to v222 for the sample problem

Confirmed that it was in GRPC mode by looking at the .tmp.out file

##############################
### START GRPC SERVER      ###
##############################

Server Executable   : MapdlGrpc.Server

Adjusted from ansys.input('analysis','inp') to ansys.input('analysis.inp') -- I was still using the /input,Fname,ext,dir formatting of APDL
It was able to successfully run the analysis and confirmed generation of the *.rst file

However, the logged apdl that is written to pymapdl_htc_log.txt for this sample problem is missing the call for the input command and only shows the following:

! APDL log script generated using PyMapdl (ansys.mapdl.core 0.63.1)
/NERR,,,-1,,
/INQUIRE,,DIRECTORY,,
/INQUIRE,,DIRECTORY,,
/INQUIRE,,DIRECTORY,,
/INQUIRE,,DIRECTORY,,
/INQUIRE,,DIRECTORY,,
FINISH,
/INQUIRE,,DIRECTORY,,
/INQUIRE,,JOBNAME,,

I confirmed this fix of not separating the name of the file from the extension works with my actual problem and analysis file. In that case, it is not logging either CDREAD or /input in this logged file.

germa89 commented 2 years ago

@emhen the /INPUT and CDREAD commands are not recorded because they are not executed using the traditional mapdl.run, they both use a input gRPC method.

I guess I could add something to get it recorded somehow.
