Cross-sectional properties using Patran Beam Library

Cross-sectional properties using Patran Beam Library

Cross-sectional properties using Patran Beam Library

(OP)
How to get cross-sectional properties (moments of inertia, area, etc) if the cross-section consists of several separate parts? I usually get cross-section properties in Patran from Beam Library using Arbitrary Shape option. But in this case (several disjoint areas) it does not work. Thank you!

RE: Cross-sectional properties using Patran Beam Library

try to connect the parts by dummy elements, as to produce a cross section of one beam

RE: Cross-sectional properties using Patran Beam Library

if you create a surface of the right cross sectional profile you can then create a custom beam section and it behaves as like one of the standard sections

Dummy element? I try to connect two surfaces by line, and I tried to create a new surface combining two initial surfaces. It did not work. See image with two surfaces. There is a hole in the plate, and I want to get information about this cross-section. Hmmmm! Catia can find everything in this case, but what about Patran?

RE: Cross-sectional properties using Patran Beam Library

if all you need are the section properties that is simple do by a hand calculation!

RE: Cross-sectional properties using Patran Beam Library

(OP)
I don't need hand calculation. I need automatically generated Patran report file with coordinates of all points, all moments of inertia, area, etc. I want to use this report file as an input to other code, so any hand calculation is not an option.

RE: Cross-sectional properties using Patran Beam Library

i have the same problem.
does anybody knows, how to solve the problem?
