  1. I I found this problem many times. I am not sure that happen because of the boundary conditions or anything else. And I imported model Optistruct file in Radioss solver, Is it ok or not? Thank you for helping!
  2. Hello, I am trying to perform impact analysis and my model contains a compression spring which works under axial loading. Which model should I choose? Will P4_SPRING be OK? Does K parameter refer to spring stiffness? Could anybody shed some light on the matter? Thanks in advance.
  3. I wish to do an impact analysis of the CRPF tube, I was just not able to understand how to do it in RADIOSS. I have used Hypermesh - Optistruct and I know about properties like PCOMP, PCOMPP. But I'm not sure what model setup should I use in RADIOSS. IMPACT_ANALYSIS_OF_CRPF_tube.pdf
  4. Hi all, I am trying to simulate the impact on a impact attenuator to be used in FSAE competition. I have referred the steps followed in the video by Altair,on YouTube,regarding the same.How ever i am facing the error during the solving time,it shows the following error,in RADIOSS Solver ERROR ==> NO RESTART FILE ERROR ID : 88 ** ERROR : TIED INTERFACE WARNING ID : 312 Could you please help me with this issue? I have attached the .out file AND .rad file also. Thank you. Run_3_0000.out
  5. Hi everyone, I'm new to radioss. I'm trying to solve an drop test analysis in radios.I have solved this by making a 0.1 mm thickness pad as rigid wall. Nut i could not get reaction force or impact load as result. somewhere in this forum i have read that creating rigidwall using RWALL gives reaction forces on the wall. So i want to ask 2 questions listed them below. Kindly answer them in any way you can. Any help is appreciated 1) Is there some way that i can get reaction forces for the current setup ( pad 0.1 mm as rigidwall) ? if yes, please be kind and let me know how i can do that. 2) If rigidwall (RWALL) is good option, hoiw do I create it? if any of you have any study material or link that you can share, please do. I'm in trouble with this one.
  6. Hello, I had a successfully running Radioss model, which I had modified by scaling down the model by a factor of 1/6 in all 3 directions X,Y and Z. When I execute a Radioss simulation with this scaled down model, the following messages are displayed -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 34785 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 13280 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 34648 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 12589 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 13006 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 13144 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 12867 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 12730 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 34786 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 13281 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 34649 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 12590 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 13007 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 13145 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 12868 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 12731 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 34787 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 36701 --CONSTANT TIME STEP 4N SHELL ELEMENT NUMBER 29495 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 38574 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 38696 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 38799 --CONSTANT TIME STEP 4N SHELL ELEMENT NUMBER 29062 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 38812 --CONSTANT TIME STEP 4N SHELL ELEMENT NUMBER 30039 --CONSTANT TIME STEP 4N SHELL ELEMENT NUMBER 28760 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 38589 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 38711 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 34503 --CONSTANT TIME STEP 4N SHELL ELEMENT NUMBER 28907 -- CONSTANT TIME STEP FOR SHELL ELEMENT NUMBER 36670 NC= 0 T= 0.0000E+00 DT= 6.7177E-05 ERR= 0.0% DM/M= 2.0371E-02 The simulation runs after these messages are displayed. I'm unable to understand why I receive this constant time step message. Please give your inputs as to how to take corrective steps to prevent the same. Thanks, Kushal.
