Hello!

I have to simulate a water flow in a pipe. I used SPH and a MAT LAW 6 for the water. I would like to have more details about the meaning of C1, C2, ..., C5 in the card of the material and which values I have to put in. 

 

Thank you so much.

 

Best regards.

    Hi Emanuele,

    The values for /MAT/LAW6 are:

    C0=C2=C3=C4=C5=0
    C1=density*(speed of sound)^2
     

    I recommend you to also go through RADIOSS User Guide on this material law.
