Optimisation - Re-Analysis

inasiopo

Dear all,

Is there a way to automatically run OSSmooth and re-analysis with optistruct.

Basically up to now we are running an optimisation then going to hypermesh, running OSSmooth, and re-running optistruct to see what deflection we get with the optimised shape.\

Can we set that at once (maybe as a batch process) so we don't have to do the whole thing, and get optimisation + Re-analysis at once?

Many thanks.

Hi @inasiopo

There is no direct way to do this.

I will check if there is any script which automates this process. If not you may have to write your own script to automate the process /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

thank you.

Yes it would be awsome if there is something.

However, would you know how can we start an analysis (optistruct) through a tcl?? what is the command 'Start optistruct analysis 'fem.fem' '

HI @inasiopo

Please find the commands to run OptiStruct using command:

and just one more...is there a way to batch run a tcl script?

HI,

Unfortunately I couldn't find any script which can automate the OSSmooth with re-analysis.

Hello again.

I am very new to this so please keep any answer to the simplest form.

I am trying to set a process with a batch file. This process will call a tcl that is looking for files (fem,sh,etc..) and then returns to finish. It looks like:

Batch --> Call tcl --> return to batch

In my batch file I have:

Set MyPath = C:\the path that files are in\
And then I am calling the tcl wich is in $MyPath$\MyTcl.tcl

That works ok up to here. But then in the tcl there are some processes that are looking for files in the same path (MyPath) and I am not sure how to use that same variable (pass the variable).

TCL looks something like:

*ossmooth_12 0 1 0 1 'C:\......\model.fem' 'C:\......\model.sh' .....

but to make the process work we need the paths in this tcl to be variables coming from the batch. So it should look something like:

*ossmooth_12 0 1 0 1 '$MyPath$\model.fem' '$MyPath$\model.sh' .....

Any help on how we can set this please?

Many thanks in advance.
