Dear all;
I want to model wave propagation in a little axisometric part with moving mesh and when i run abaqus ; i recieve an error that say you should define bulk modulus considering i defined elastic properties & density ; when i enter bulk modulus and run abaqus i will recieve this error: the option *acoustic medium completely defines the material behavior & it can't be used with an option that defines part of a material's behavior. when i remove elastic properties abaqus will analyse until end but i would not have any contour ; any plot...
what should i do ?? anyone have such a experience?? please help me![[sad]](/data/assets/smilies/sad.gif "[sad] [sad]")
