about mesh stiffness
 

in CFX,we can set the mesh stiffness.now i want to konw how to set mesh stiffness in star ccm+?

you may need to put that into context. star-ccm doesn't have a feature called mesh stiffness. a quick google search suggested that it has to do with moving mesh.

perhaps if you explain what you are modeling and what mesh stiffness is controlling for you in CFX, someone might be able to explain how to handle it in star-ccm.
