How to reset selected variables in TCL

Hie everybody

When I loop over several subcases to post treat the stresses, I need to reset variables otherwise, the results , I can obtain in the first loop, remain in the next loops : thus it is impossible to get the results I want.

I tried to use the command : 'namespace delete varaible' but it deletes all

thanks for your replies

HI,

You can loop again and unset pertcular variable instead of deleting whole namespace.
