Hello everyone, i just want to know how to see the shear stress in tau_xy and tau_xz direction. I used optistructe as my solver. I only see "max shear" as an option but the result didnt expect as it shoud. the modell is loaded with a lateral force and has a fixed joint.
Hello everyone, I am new to Hypermesh and have a question regarding the ZOFFS option. Also, as an understanding check, can you verify that I understand the hierarchy correctly: Understanding Check: The hierarchy is as follows Component, Property, Material, System, etc. Properties must have a Material assigned (to supply to the component) Properties must have an Element Type assigned (to supply to the component) Correct? Question: I cannot see the ZOFFs option in the Properties Card Edit. I have selected elements and assigned them their element types (CQUAD4 fo example). But when I go to add a ZOFF in the Property Card Edit window, the option does not show. From what I have read online, it seems it should show on the property Card Edit. It does however show if go to Element Card Edit, select elements, click "edit". Other info: I am using PSHELLS, assigned to the Property. I am in the Nastran profile. I want to make sure that I am setting everything up correctly. Thank you for your help!
Attached is a Hypermesh deck of a structure whose mass I’m trying to minimize. The structure has a square shaped core covered on the top and bottom by composite facesheets. Shell elements have been used for modeling. The size of the square and the thickness of its wall determine the buckling characteristics of the facesheets. I’ve modeled using a square of side 6mm and its wall thickness is 1.5 mm (shown in the snapshot below). By varying the size of this square and changing the wall thickness, I’m looking to minimse the mass, the constraint being that the buckling factor must always be greater than 1. Could you please help me achieve my objective? Thanks, Kushal Agarwal. square_foam_opti.hm
