Re: Slow Database Loading

So it's very hard to tell why it is doing that.
Please send me the MPCO files (if small) or send me the SCD (and I will generate the output MPCO). Just to see if I can reproduce this issue.

Re: convergence problem

After several attempts I managed to obtain satisfactory results but the analysis always stops due to convergence problems. How can I fix them? I made some changes in the analysis. But the most important change is that you used LoadControl while I used DisplacementControl. Note that you will never m...

Re: Slow Database Loading

This is really strange. If the first time you read the DB it was saved in a SSD (Solid State Disk) and then you moved it into a standard HDD, then it would make sense. If this is not the case, try to open the System Registry Editor (type the regedit command in the windows search bar) Then navitate t...

Re: Parameter study

replace this code in your BEGIN LOOP: puts "BEGIN PARAMETRIC ANALYSIS LOOP ..." # I moved this on top, because we need it to write the definitions.tcl file only # on process 0 set PID [getPID] # declare 9 time series and rayleigh damping commands, 1 for each analysis set time_series_list {\ "timeSer...

Re: Failure of a Masonry Infill in RC Frame Analysis

So it is perfectly normal. When you change your parameters, it may happen that your model is (for example) more brittle, and you may need to play with the nonlinear analysis parameters a bit more, to obtain convergence. This is what usually happen in nonlinear analysis. They are not guaranteed to co...

Re: Integrator and Analyze options

Dear Asad, It is extreamly simple... If you are doing a load control, it does not matter what is the displacement you applied (via a SP command). The only important thing is the timeSeries. If the timeSeries goes from t = 0, to t = 1 then the duration should be 1 and the number of increments, depend...

Re: In which direction the central node mass of the infill should be assigned ?

I do not really understand your question... If you are using the STKO-automatism (MasonryInfillWallMaterial), you just input the gamma_inf, that is the wall density and it will take care of assigning the mass at the mid-node. The mass should be assigned in the DOF along the out-of-plane direction of...

Re: Slow Database Loading

Dear Vefa,
this is really strange... Does it happen all the times? or only sporadically?

Re: Failure of a Masonry Infill in RC Frame Analysis

You should be more specific. What do you mean? are you having convergence issues?
I just tested the files downloaded from our webinar page and the model converges to the end.

Re: Layered Shell

It is correct, the frist layer in the TABLE is place at the bottom of the shell, while the last one in the TABLE goes to the top.
To visualize the layers in the post processors, you need to use a fiber plot, where you can visualize results such as section.fiber.strain or section.fiber.stress
