  1. Frequency Response Analysis

    thank you @Prakash Pagadala
  2. Frequency Response Analysis

    Hi @Prakash Pagadala, the load spectrum in time domain is: 0 psi @ t=0 sec; 3000 psi @ t=1 sec; 0 psi @ t=2 sec. What I put on TABLED1 and DAREA? In DAREA, i can not allocate the pressure (3000 psi) in right way, because there isn't the possibility (i'm not expert in dynamic analyzes !) to assign a pressure on a cylindrical coord system (in radial direction) or normal to sufaces. is it possible to use a generic PLOAD4 to assign this pressure and refer it on RLOAD card? Thank's for your support.

  4. Frequency Response Analysis

    Hi, I must perfom a Frequency Response Analysis. In particular i've a pressurized cylinder subject to a Impulse load with frequency of 1 Hz and magnitude 0 - 3000 psi - 0 (sin function load). i want the response on first 5 natural modal frequency. how i must set the analysis ? Thank you

  6. Check element 3D

    I want to konw if there is a possibility to have a summary in a txt fle or other, where there are listed the results of element verifcation (like for 2D elems).
  7. Check element 3D

    is there a chance to export the tetra elements check on a txt file or other ?
