Ok you need to explain which function call gives you this. Usually this comes from the scheme interpreter. It means that some scheme function received the wrong arguments.
Please explain more.

Code:

(car "xxx") ; When using 'car', its argument should be a list.

I received this same error message when trying to add source and sink terms to separate cell zones. It was confusing me because sometimes I would receive the error and sometimes I wouldn't.

I talked with ANSYS customer support today and they told me that it had to do with problems with the code when using the GUI. Their suggestion was to close Fluent and start it up again.

I had already tried this once and it didn't help. However, at the suggestion of the customer service rep I tried it again and it worked the 2nd time. I was able to add the source and sink terms and did not receive an error.

I don't know if this will help for every case where this error message appears, but it's worth a try.

I also received this error for a double periodic domain, when trying to plot contour or define periodic planes; my domain is a slice of a tube translational periodic in z direction and rotational periodic around z axis.

However I have no problems in postprocessing with CFD-POST.

.

I don't get any problem while defining the periodic planes or contour plot on periodic boundaries.

Even I had the same error message displayed.
Closing the fluent and restarting and importing the case/data/mesh file fixed the issue for me.
