hi everyone
I was wondering if you would mind helping me to run the simulation for steel casting,
now i face a problem and thats this error
-feature: stationary solver1(sol1/s1)
-error: failed to evaluate expressio.
please let me know what can I do.

Also I could find this in the error part:

Hi
it says you have not defined the "mu" in your material,, always check the material properties to see if all required data are there "red STOP" flags should be filled in and cleared BEFORE you solve, else you get these kind of messages ;)
Note that if you change the material properties, you might ask for new material properties, therefore always recheck the material nodes before solving and after having changed your BC in the model

Good luck
