Geostar Scripts 1

[cmarotta]

Is there a way to write a script or macro to run consecutive transient thermal analyses in Geostar? Currently, we start an analysis with 1 second time steps for 200 seconds, then restart the analysis with longer time steps.

Hello Dear cmarotta;
I dont know your answer sorry, but can you write about Geastar please, what is it? why it is at the background of cosmos? how it works and what kind of analysis it can solve?
do you have any toterials about that?
thank you

Hello ENzo36:

Let me see if I can explain this coherently. Geostar is the "engine" that Cosmos Works (now called SolidWorks Simulation) uses to solve FEA problems. You can run Geostar separately. It has much more capability that SolidWorks Simulation but is much more difficult to use. Some of the things you can do in Geostar but not SolidWorks Simulation are manually create a mesh, choose from a much larger element library, and choose from a larger set of solvers with more solver options. There is a tutorial under the Geostar help menu.

You can probably use SolidWorks Simulation for most of your analysis. The only reason we use Geostar is because we have some problems involving radiation heat transfer on complex assemblies and we've never gotten SolidWorks Simulation to run them correctly.

It seems that SolidWorks Simulation gets more capability added to it with every release, so eventualy maybe it will replace Geostar? I don't really know as I don't work for SolidWorks.

Dear cmarotta:
Thank you for discotion;its full enough, sometimes i want to use the Geostar but it has no toterials and its help is not applicable, its seem that with this property Geo is good choose for nonlinear analysis, as you write solid simulation is not good choose for large elements and there is no options for manually mesh creating.but it cover a varity of analysis that qiuck preprocess and BC definitions are its awesome property, its realy based for "What if" designing. i use ANSYS too, it has too more options for both linear & Nonlinear analysis like Geo, when i try to draw a circle in Geo, it gave me a form that you can see it at below, all of this inputs just for simple circle drawing!!please someone tell me its a kidding!

what is your opinion?

Hi
Oops! This is buckling test that I do it by Geo for first time; my test has a beam with this property;
Beam height: 100
Cross section area: 100 (10x10)
Poisson's Ratio PRXY: 0.3
Young's modulus EX: 200000
Applied force: 1 N
The results:
Max Disp: 0.5
BLF: 2e-8 for mode Num 1
