Hi, Would like to know whether it is possible to do a drop test analysis just using Ansys Structural? Has anyone tried before? What is the limitations and how is it different from using LS-DYNA? Thanks & Regards.

Hi, We usually get stress concentations in bolt holes. If the FE result shows that the stress at these holes is greater than the UTS of the material, does it mean that the whole structural will fail? Sometimes, bolt holes are ignored during simplification of the models, so how to know...

Hi, What is the advantage of having a class-3B tread compared to a normal thread? Thanks & Regards.

Hi, Is there any resources on performing Coupled Load Analysis using Patran/Nastran? Thanks & Regards.

Hi, I would like to know whether there is any difference in the weld strength if a) welding without any heat treatment b) welding after heat treatment c) welding prior to heat treatment and what's the reason? Thanks & Regards.

Hi, Is there any examples on how to do substructuring in Patran available online? Has anybody done that before, any advice? Thanks & Regards.

Hi, I'm modelling a thin aerofoil sheet using plate elements. Would like to know if there is an equivalent thickness for aerofoil shape. Thanks & Regards.

Hi, I would like to know if there is any documentation on the strength of laser weld. Is it about 80% of the material strength? Regards.

Hi, I would like to know if there is any documentation on the strength of laser weld. Is it about 80% of the material strength? Regards.

Hi, I would like to know if anyone has experience regarding heat treatment before and after machining process. From my knowledge, if heat treatment were to be done before machining process, special tool bit must be required because the material will be hardened therefore, typically, heat...

Hi, I'm doing a structural analysis on a Wind Tunnel Model. Does anyone has any idea the percentage difference in applying sectional force loadings vs pressure distribution loadings? Regards.

Hi, I have a dataset of more than 10,000 pressure pts in X,Y and Z coord. And I need to input this pressure field as loadings. However, these pressure pts might not coincide with my meshing (node pts or element surface). Is this possible? What is the best way to do this? Regards.

Hi, Does anybody knows the difference between force, distributed force, CID distributed force, pressure in Patran? Regards.

Hi, Has anyone tried to assign properties (beam, 1D) to Bar3 elements before? I keep getting an error saying bar3 topologies is not valid for this element type. May I know how can I assign properties to bar3 elements Thanks & Regards.

Hi, Would like to know, other than heating, is there any chemical that can remove Loctite 620? Regards.

Hi, I'm trying to create an isomesh element for a solid which is irregularly shaped. However, there is always the error message saying the solid is not isoparametric, therefore unable to mesh using isomesh. 1) Would like to know how to get an isoparametric object from an irregular shaped...

Hi, I'm doing a transient analysis and random analysis on a 20,000 element model with Nastran as solver. The result files (.f06 and .xdb) I obtained are both very huge, in the area of about 10GB! I wonder if that is common. I managed to get a result for transient after reducing time-step...

Hi, I have a box with some components in them attached to the box by means of bolts, screws. Furthermore, the box has a cover with is screwed down to secure it. Because of the screws attachments, I have lots of holes in my model. Also, components are not of regular shapes. Would like to know...

Hi, I just imported a parasolid file into Patran but was unable to clean up the model using geometry->edit->feature because the feature list is empty. I am unable to just import the model as a UG file because the UG version i'm using is NX2 while i think Patran 2003r1 only support up...
