evaluating inside volume & export deform geometry

maa_generals · July 8, 2016, 14:55

Hi friends,

I'm simulating a container and it deforms under pressure.i have to evaluate the inside volume.
in other words,i have a deformable pack filled with a gas in special pressure and I want to know how much gas is in the pack.

i try static structural for making deformation and export a .cdb file to use it in a FE modeler and make a parasolid object of the deformed shape.then open that in geometry and use fill tool.

but the parasolid have lots of gaps and uncoordinated surfaces!!
also i have surfaces in parasolid file and how can i use them as solids??!!!!

any suggestion???
or other ways to solve the problem??!!

can anybody help me with this please???!!!
thanks a lot...

if anybody has any idea please doesn't hesitate...
thanks...

If you have shell model then, export the deformed file as .STL file and then open that in SpaceClaim and merge all faces into 1 face. Then you can export that file as .Step file and import in any cad program then for example in Solidedge by using repair and then combine option make solid volume of your deformed geometry then from properties you can calculate the deformed volume.

No idea about solid geometry. Even I am searching for it. If you know please share !

Thanks !
