Thanks for the reply. The analysis works fine and so the node reaction recorders , only the recorders for prestrained materials do not work, so if I only Initstrain my steel and leave concrete unstrained initially, then recorders for steel would not work while for concrete work just fine. Is there a...

Hi all; I'm modelling a prestressed pile and I'm using InitStrainMaterial to introduce prestressing strains to my material. here is my material model for strands: uniaxialMaterial ElasticPPGap 1 200e9 1700e6 0.0001 0.018 uniaxialMaterial InitStrainMaterial 2 1 0.006 So basically I'm introducing an i...

Thanks for the hints. About the difference between periods on different computers, it only happens for some models with really small penalty values. As for the parallel processing, I couldn't find the problem however I'm manually assigning each run a processor and it works. I wish I could copy the w...

Hi all, I'm trying to run a opensees bridge model on local linux cluster server. This bridge model code is developed for parametric studies as the ultimate goal is the reliability analysis, thus the same script will run with new set of parameters each time. I use 3d contact elements in the model I n...

Thanks!

Hi!
I've got a question about element recorders for fiber sections. when defining recorders for circular sections, should I mention fiber coordinates in Y-Z or R-Theta coordinates?

Thank you in advance

just one more question, for circular sections, should I mention Y-Z location of the fiber or R-Theta??

Thanks for your tip! it should be the integration point number not the section number.

it is the section number.

Thanks for your quick reply. I tried all below combinations , none of them worked: recorder Element -file ele348Force.out -time -ele 348 section 6 fiber 0.33 0.33 22 stress recorder Element -file ele348Force.out -time -ele 348 section 6 fiber 0.33 0.33 22 Stress recorder Element -file ele348Force.ou...

I've got a problem with my element recorders for fiber section elements, output file only contains timesteps and nothing else! Any hints and suggestions will be appreciated. here is one of the Recorders: recorder Element -file ele348Force.out -time -ele 348 section 6 fiber 0.33 0.33 22 force and her...

Hi, I'm working on a bridge model and I need to verify my material models for different components. I'm using a 2DOF truss element to verify my Uniaxial material models, some of which include an initial gap. I've tried displacement control, load control and Arc length methods to test those materials...
