  1. i need to get frequency of 20<= f <= 30 hz checkmat is there in hmv9.0 also
  2. yes sir i got it, its there in hmv9.0 also. i tried but its giving different results. There is an issue with the material property matrix (Gij)- it fails the material check: can you send me the results
  3. good evening sir, i have downloaded hwv19 i am not finding any checkmat thank you sir
  4. Good Evening sir, i really thank you for the support that i am having from you. it means a lot. i want to get clarity, is this the problem of material property value input G13 , G23 ......or else. i don't find any checkmat in hypermesh v9.0 as i am using in conjunction with nastran. thank you sir
  5. Good Morning Sir, by accepting your advice, i want to convey to you that. i am getting some different results than expected. as I am executing a model referring a paper. the material for face and core is aluminum. i am using MAT1 for face and MAT9 for core. PSHELL PSOLID i am suppose to get the frequency 20<= f <= 30 in Hz i am getting 1.36Hz for 25 element size 0.7809 hz for 20 element size Geometric Details A =1828.8mm B =1219.2mm Tc =6.35mm Tf =0.4064mm a/b =1.5 Material Properties Face Aluminum Aluminum Core E= 68.94 GPa G23 = 51.71 e-3 GPa G= 25.92 GPa G13 = 134.45 e-3 GPa V= 0.33 P= 3.05E-09 tn/mm3 p = 1.34 e-10 tn/mm3 121.8318 kg/m3 Cards Used MAT 1 MAT9 PSHELL PSOLID SSS Boundary Condition correct me if anything is wrong thank you sir 287ssss44directdensity20mmelement.bdf 287ssss44directdensity25mmelement1.bdf
  6. I want execute the model the bdf file is larger than the limit so i couldn't uploaded. hope you understand. it is for the modal analysis. thank you sir 287.doc
  7. sir also i want to apply simply supported boundary conditions for plate on all four sides. plate will have only rotation not translation on all the edges is it correct, if not correct me. thanking you
  8. here is the bdf file i am getting error as USER FATAL MESSAGE 9073 (SUBDMAP PHASE0) MULTIPLE BOUNDARY CONDITIONS IN NORMAL MODES ANALYSIS REQUIRES THE BC=N COMMAND IN EACH RESIDUAL STRUCTURE SUBCASE.
  9. On 11/2/2019 at 1:01 AM, Hyperman said: I am solving plate for modal ansly with two sides clamped two sides free And One sideclamped three sides free How to apply two constraints in a single model It says specify bc=n ... Which I don't know
  10. I am getting error sir Let me know where I am getting wrong
