My problem it is the next one
I run the model without error, only warnings, and the calculation finish
I get the following message:
One or more result files are not compatible with the current model and cannot be loaded.
The model may have been modified after these results were created or this .std has been saved over another file leaving the analysis results of the previous mode.
Do you wish to delete these files? ....
I did not change the model while running.

Thanks in advance,
