post processing
 

Hi:

I am simulating the flow in a minisize centrifugal pump with fluent.While I display the relatie velocity (for a wall or surface)in post processing ,a message appears in fluent:"error:floating point error:invalid number¡±¡£In such case,I cannot get the relative velociy .(even if i get the relative velocity ,it is same as the absolute velocity.)Who knows the reason and how to solve it?It is the relative which i want to get.
