  1. Sir,

    I am doing a rollover analysis of a bus, for that i have given initial velocity as 10mm/s in the SET, but its just deforming at the place where the velocity is given

    Can u just help me out on what I should do to make the bus rollover on the platform.

     

    Thankyou

  2. Hello Prakash,

    I am trying to simulate a torsional rigidity test on a FSAE race car chassis and I need help assigning proper beam end releases at the suspension nodes.

    I am trying to simulate a ball joint with this configuration - 

    pin a  = 456 and pin b = 0. I this correct as I am unable to get the desired motion in the setup.

    The hw help says pin a and b should be values which are not intended to transmit forces. Should the pin a be  = 123 instead?

     

    Thank you

  3. @Ahanvoth The attached model is simple plate (5mm) with pressure applied. I have included gauge optimization in the model which varies thickness from 5mm to 0.1mm. The attached h3d files have thickness variations and displacement results. You can study the results for corresponding change in thickness.
  4. @harikrushna E and Nu are minimum requirement to form a stiffness matrix - technically... Theoretically- Nu defines the way material will change its shape. Hooke's Law
  5. Hi @Mahantesh Looks like the load on model is zero. Make sure you apply loads on your model.
  6. Hi, How many does your model contain? I think due to optimization the run is taking long. Can you check if it is the same with analysis only (without optimization)?
  7. @riham1994 Can you explain what you mean by just suspension? You can do a frontal car analysis which includes front suspension
  8. @wumindao You will end up with this message when you have CHBDYE on design space CHBDYE can't be applied in topology or free-size design domain.
  9. @wumindao No Problem

  11. @wumindao There is no heat flux applied in your new model. Create CHBDYE and apply heat flux (QBDY) on our model.
  12. Hi, I am not sure what you are trying to optimize. I see only one response which is volume fraction referenced in both objective and constraint which is not practical. If you are idea to control thermal compliance create another response for Thermal compliance and use it as objective or constraint. 2) There is no thickness for non design property 3) I think load collector heat flux is empty no heat flux is seen in your model.
  13. @wumindao Can you share the model file,please?
  14. Hi, You can do a gauge optimization with minimum and maximum thickness. here is a sample file. size_s1.h3d size_des.h3d size.fem
  15. Hi, Which solver are you using for RMS analysis? All the simulation happens with solver and the results are stored in result based on user input.
