Need help in Composite Post-processing Operations
Hello,
Having issue with doing post-processing op of a composite part in HV.
Created this component in HM. The zero degrees plies (or Material Orientation direction is along +Z axis). The set up is pretty simple. Fixed on one side and an axial load on the other side. The solver I used is MSC Nastran and PCOMPG cards were used to define laminate.
<?xml version="1.0" encoding="UTF-8"?>
The cross-section of the component showing the laminate.
Selected 'Composite' option during the initial setup where I point out to model & results file.
The option Global System (projection: None) is greyed out. Was under the impression that I could select 'Projection Active' (or something similar) and use the Global Z direction to tell HV to transform Ply 1 XX results. This is how I usually post-process in Patran.
Next I created a user defined coord system and had HV point it out to transform (System id =1). But still I am not getting any output. What am I doing wrong?

I also want to add that I am able to obtain any deformation pattern in Hyperview. Although HV shows the Contour values of Deformation in the model, somehow it is not showing the deformed shape. Supposed to have a slight bend as shown below in MSC Patran.

Hi,
I have attached a copy of the both bdf file & op2. Hopefully you'll have better luck than I did.
Thx,...

Hi Prakash,
Yes, I am getting results in Analysis System.
<?xml version="1.0" encoding="UTF-8"?>
What does this DEFORM function do in Hypermesh? I was not able to find any references in Hypermesh Documentation. If I check the Deform check box, I am supposed to select a Load Collector. Should this be checked to obtain Deformation shape?
<?xml version="1.0" encoding="UTF-8"?>
Also, in Hyperview I created a Projection Rule where the Global Primary Axis points to or transformed to Z direction as shown below:
Still no joy in getting Ply results displayed

Hi Prakash,
Are you having similar issues I am having at my end? Hoping for suggestions on how to resolve the above.

Hi @Burner2k
Deform defines axial deformation for 1D elements.
I will check if I can reproduce the same at my end and I will share my findings.

Hi @Burner2k
I see that projection rule works for element stress and not for composite stress.
I am going to check with experts on this.

Hi,
Did not want to start another thread but I dunno why I am not able to plot deformation shape in Hyperview. I even made a very simple Test case of a 2D Isotropic plate subjected to axial load. But I just not able to obtain the deformation shape on HV.
I am attaching the bdf & op2 files. I want to get some resolution on this soon. Please help.

Hi @Burner2k
Do you see displacement and stress contour?
If yes, change the Deformation shape scale factor.

Hi Prakash,
I was just about to post that I think HV was showing the deformed shape but I had to adjust the scale of it. I will investigate the same on other models including the composite one and report back.
In the mean time, I would appreciate if you could do give a glance on why Stress Global Projection for individual plies are not working.
Thanks for your reply. Appreciate the continued support on this forum.

^^Cool man. Thanks for the update...

Hi Prakash,
Any updates from developers about the composite transformation issue?
0 -
No, not yet.

Hi @Burner2k
So here is an update:
Try after loading both model file and .op2 file in HyperView with Advanced Option
0 -
^^What exactly does the above mean? I do load both files IIRC. I point out to bdf file & op2 files and then to 'Composite' when I first start HV. Unless that has to be repeated else where...I would say that I am doing that already. I am currently away from computer. Will try to post pictures later.

HI,
Yes I can see that from your first image.
Please use Advanced instead of composite Result Math template.

Hi Prakash,
I did a quick check per your suggestion using Advanced template instead of Composite and it seems to work. I forgot to do a check on transformation of results for a User Defined Coord Sys, but I'll take it that works as well while using Advanced template.
Thanks for your support and resolution. Appreciate it a lot.

Hi @Burner2k
Please share your finding regarding the same.
If you feel something is NOT correct, please do let us know...
