Hi All, I have SOLID45 element with two material properties 1 and 2. I build my structural model and mesh it with appropriate materials. Whenn I use a ETCHG,STT command then all the material in the SOLID70 model changes to material 2. What is the correct way of doing this? Regards

Thanks @cbrn I was able to figure out

Hi @cbrn, So what should I do if I want to user Backwar Euler method or Crank-Nicholson method? Regards Harsh Nandan

Hi, So, how do I know which time stepping scheme has been follwoed as I need to document it? Regards

Hi All, Whenever I try to do a transient analysis on Plane55 element using following code , I see a popup during the iteration on which "Nonlinear Solution" is written. I am assuming my system to be linear, can someone advise me why this "nonlinear Solution" is being shown and is there some way...

Thanks for the explanation Alex.

Hi @mihaiupb Should wl_solve be substituted by wall2-wall1. It will be great if you can explain how are you formating the wall time in hrs min and seconds. Thanks for your help Regards

Hi, Can some one tell how can I capture the run-time of an analysis. Regards

Hi Brian The description of ldread command is as follows: LDREAD, Lab, LSTEP, SBSTEP, TIME, KIMG, Fname, Ext, Lab = TEMP -- Temperatures from a thermal analysis applied as body force loads [BF] in a structural analysis, an explicit dynamic analysis, or other type of analysis. Can also be...

Hi, @Stringmaker I tried the following set of commands, where I read a temperature of 500 K from the table. I am doing a transient thermal analysis in this complicated way as I need to stick in few other analysis after every cycle of transient analysis. /PREP7 length=1.0 height=1.0...

Hi All, Can anyone tell when file.rth gets populated during transient thermal analysis as I am need to pick up temperature distribution in the body at the end of transient analysis using ldread command. Thanks and Regards

Hi Stringmaker and cbrn, I agree with the fact that is a computationally expensive and it looks like an unnecessary computation. That is why I want to do this and once I have the temporal data of temperature and modal characteristic, I will like to fit a stochastic model to this and hope that...

Hi, I am performing a coupled analysis, in which I am trying to analyze effect of temperature on the modal frequencies of the structure. For this the logic I am thinking of is to do a transient thermal analysis with controlled time step and then move to modal analysis after every time step...

Thanks

Hi Brian, Thanks for you comments. That helped me in understanding my mistake. I am working on a Sun Solaris (IRIX OS) machine and using a CSV file solves my prblem on windows machine, but I am still facing the same error on SUN machine. Do you have any information regarding this? I greatly...
