评论： Joe Cullen 2020-12-17

I am trying to run a co-simulation with a modeling software called AMESim, which generates a *.mexw64 file. I'm using an s-function as the interface to the mex file in Simulink. The simulation works just fine when the models are all in the current working directory. However, when i put them down one level in the model architecture (one folder deep, which is on the matlab path) the so-simulation fails with the following error:

Error in 'PlantModel/S-Function' while executing C MEX S-function 'PlantModel_', (mdlInitializeConditions), at time 0.0. Caused by: Simcenter Amesim mexfunction PlantModel_ did an abnormal exit!_

Note: PlantModel_ is the *.mexw64 file

Did u solve the problem？I met the same one today.

No, I have not found a solution other than to change the matlab directory to where the amesim model is stored or move the amesim model up to working directory folder.
