  1. Pload in optistruct and Radioss

    Hi George, but if I need a function Pressure vs height where pressure is calculate, in accordance with Pascal's Law where ? Is it possible? Thank you! Best regards
  2. Pload in optistruct and Radioss

    Hi George, how can I apply PLOAD4 in Radioss?
  3. SPH formulation - box deformation

    Hi George, thank you very much for your suggestion. A last question: how can I see the particles not like point but big, like in your gif? Thanks
  4. SPH formulation - box deformation

    Hi George, I'm very thankful for your replay! No, I'm actually not looking for a continuos flow; I used the SPH method for meshing water, because I want to see the deformation of a box full of liquid. I think an alternative solution could be to apply a variable pressure inside the box, increasing with depth and applied to different contact surface (see the fig. attach), but I'd like to try the SPC method, if it is possible. So I need that the particles mantain their pitch and employ pressure on box's wall. Any suggestion? Thanks a lot
  5. Hello Everybody, I'm trying to use SPH Method with Radioss. I would like to determinate the deformation of a box full of water. I've modeled SPH Particles of water as simple cubic and I've used interface type 7 between water and box. Loads: lock of the base of box and gravity load to water particles. The simulation run without error but results are different than expected: pressure is not uniformly distributed becuase particles don't mantain the initial pitch. What is the error? In attach the .hm file. Could someone help me, please? Thanks in advance. prova_acqua.hm
  6. RADIOSS-MATERIAL LAW

    Hi Ashu, thank you for your answer. I know any kind of help but I didn't find it so useful. I'm trying to do non linear geometric analysis using radioss but I'm not sure I'm doing right. I don't understand your 3rd question. Could you explain it? Thanks.
  7. RADIOSS-MATERIAL LAW

    Hi, I have to simulate a component made by PA66 and it is exposed to a change of temperature and to thermal expansion. I've stress\strain curves temperature dependent and I'm looking for a material law where I can insert this curves. I'm trying to use law74 because I saw it is a material temperature dependent but I don't know what is the meaning of fct_ID_E, or C_E. Can you help me please? Is law74 correct or there is one better? Thanks in advance
