Re: LinearSysofEqn failed

Thanks,
I think I found the problem. The Brick elements can't have 6DOF.
Can I have to model builder for example one for a 3DOF system and one for 6DOF system in one script?

LinearSysofEqn failed

Hi, I am modeling a very simple continuum system under dynamic load. very simple cubic shape with fixed base and uniform excitation. It works fine when my ndof is 3 but it gives error in ndof=6 saying "ProfileSPDLinDirectSolver::solve() - aii (0, (i, aii): (54,0) WARNING NewtonRaphson::solveCurrentS...

Re: Memory Error

Hi Frank, Did you get a chance to look at my script to see where the source memory error is?

Re: Memory Error

Thanks Frank,

It seems that the memory usage keeps increasing. My model is very simple it is only one element.
Here is the script.

Memory Error

Hi, I have a problem when I am running my model in opensees. I have a loop where certain analysis is repeated inside. When I increase the number of loop increments I get the "out of memory" error while I don't have it if the number of the loop increment is lower than a certain value. Even when I run...

zero the displacements and ...

Hi,

After performing static analysis and before dynamic analysis, I want to zero the displacements, velocities and accelerations while keeping the element parameters such as stresses. Is there a way or a command to do that?

Thanks,
Majid

Re: reading from a file

Thanks Frank, It was a great help. I have still one problem in this regard. These commands work perfectly when I have a *.txt file ready before running the program, but it doesn't work when I make the *.txt file inside the code. For example if I make a *.txt file using a recorder and then analyze th...

stress control

Hi,

Is there a way to track the stress value at a specific gauss point during the analysis?
"eleResponse" command put all the values in a file. Is there a way to get the values directly?

Thanks,
Majid

reading from a file

Hi,

I want to read values from a file. Can anyone tell me what command I should use?
The command "read" gets the whole numbers from a file as a string but I want numbers in an array or in a numerical format.

Thanks,
Majid

Re: Simple shear test under constant amplitude CSR condition

Hi,

I am trying to model the same problem.
How did you model a simple shear test?
Where and how did you applied the motion?

Thanks,
Majid
