Hi evryone, i'm studing the modal frequency response of a rotating impeller on Nx 10.0 ( see the picture bellow). but i could not define any forcing frequiencies. so i keep getting this erreur message:
ERROR : No forcing frequencies defined in step "Subcase - Modal Frequency 1".
Forcing frequencies are required for this frequency response solution step.
ACTION: Define forcing frequencies in the Solution Step Attributes.
Any help would be great.
Here you will find the sim and fem part:
You need to define forcing frequencies (FREQ cards). Kindly define in case control section of your solution or subcase.
