  1. Now, It shows buckling modes by making the load GRAV in -Z direction. but it still does not show stress and displacement due to buckling
  2. I want to create the buckling analysis for the same. I have used GRAV card for loading. I want to carry out the buckling for the same. But I am not able to see the results for linear buckling. Will you please help to resolve my problem. buckling.fem
  3. Is it Possible to mesh a cone with hex elements? cone height h = 4.1 and r=2 -Nirav Modi -Thank you
  4. I want to do for Acceleration(PSDF)=All . but I also want PSDF-acceleration response curve for the base node and some selcted nodes. in a single graph for comparison . In my friend's pc, using the same version of hypermesh, it doesn't show the option of Random(1) in acceleration and displacement ( in Global_Output_request ). It only shows for stress only. I also tried to change solver template but it was of no use. Please help me with that ! and your attachment Gr.m.s is not properly attached. I am unable to open it.
  5. I also want PSD respose curve at some selected node also. I also want g r.ms value at base and some selected node . How can i get that ? -Nirav Modi -Thank you
  6. Will you Please elaborate about cards like PARAM,G? and How to specify the value of that? can you please make an FEM file which is consistent with my inputs? So, It would be very helpful and I can co-relate easily. -Thank you -Nirav Modi
  7. Hello sir, I am currently using MSC Nastran, Patran for random response anlysis because it is quite easy. I want to do that in hypermesh/optistruct. but the tutoril does not match with my requirement. 1. I have input in terms of acceleration as base excitation. 2. I have Frequency Input 20 to 2000 Hz with 100Hz increment. 3. I have a critical damping condition of 0.3. 4. I have PSD Input as follow 20 Hz- 0.056 100Hz - 0.28 700Hz- 0.28 2000 Hz- 0.0343 5. I want peak g rms and g rms at few nodes. I also want Von-Mises stress.
