1. How to output reaction force frequency response?

Hello everyone, A frequency response analysis was done, and I want to get the reaction force frequency response at the SPC nodes. The following control cards were used. However, I cannot get the reaction force frequency response. FORMAT OPTI FORMAT H3D OUTPUT,HGFREQ,ALL SPCFORCE(H3D,REAL) = 1 Which output control should be used to get the reaction force frequency response?
2. Reaction force and Moment

How to calculate reaction force and moment at various constraints in nonlinear dynamic analysis.? suggest with proper output block?
3. Reaction force of bolt

Hello, I want to find the reaction force in bolt.
4. Rigid wall (RWALL) in radios

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.
5. Reaction forces half of expected

Hi, I set up this test model to analyse how forces and supports are used. The right hand face is rigidly supported and all translations and rotations are constrained. The left hand face has a 1 N load applied in the z direction as shown. This problem is essentially a cantilever beam with a fixed end. Therefore with only one support and one force the reaction force at the support should register as 1N, but it registers as 0.5 N. Why is this? I have attached the file below, working with Inspire 2018.3 Many thanks, Caleb test-model.stmod
