Trying to run a nonlinear dogbone macro simulation in Multiscale designer
I have simulate in inspire mold the filling of a dogbone to obtain the fiber orientation tensor, now i want to introduce it on the injection molding-mapped input to analyse a nonlinear macro simulation of a dogbone in MDS, the problem is that i don't know which files i need to browse in the laminate for injection molding-mapped input set up. The second file that is fiber orientation result file and must be with the extension .xml i suppose that is the .xml that the injection moldong exports and we used for the mapping process in the webinar. But the first file that is Mfg mesh file and must be with the extension .inp, i don't know where i can find, create or export it and im really lost at this step.
Please, could you explain or help me to learn to make this step properly?
Thanks in advance.

the webinar #3 here shows you the process, if I recall correctly:
https://web.altair.com/composites-webinars
In summary:
- run molding simulation, making sure 'fiber properties' are present, and fiber orientation output is requested
- molding will generate .xml orientation tensor and a .fem mesh file in the run folder
- then go to HM, and use the 'fields' operator to map the .xml orientation to your structural mesh, and then export a .h5 file with the mapped orientation
- once you have the .h5, go back to MDS and setup the macro solver model, by supplying the .h5 orientation file, and your structural .fem mesh

Hey
Thank you for your helpfull comment. However, for me it is still unclear...
I did the following steps based on the webinar "Simulating the Performance of Fiber-Reinforced Injection Molded Parts":
1. Perform filling simulation with Inspire Mold to get FOT (c2mRun_fiber_elemental_results.xml)
2. Import structural mesh and cfd mesh into HM and map the FOT to structural mesh
3. Then go over to MultiScale Designer and create deterministic materia model for PA6 GF.... And here comes the point i don't get... In the webinar three "standard" Layups are defined and calculated. Fine, but how to proceed to get the derived homogenized material to the existing hm model??? Solver Intefaces -> Optistruct -> MAT9 (Homogenized Materials) -> Export. And then?
How is the fiber orientation in my model and the create materials are linked? The MultiScale designer exports the following files: Macro Tension, Layup1 Tension, Layup2, Layup3 and the same for compression. I searched a lot but did not found anythink helpfull...
Thank you so much for your help!

Hi
I am also facing the similar issue which combining the results of multiscale designer and inspire mold results. I followed following steps
1. Ran fiber orientation simulation in inspire mold.
2. Mapped fiber orientation in optistruct using field method.
3. But now while defining material in multiscale designer we need to assign fiber orientation tensor in 2nd step (Linear material characterization). what values we have to put here, and how it we getting attached to mapped fiber orientation file (.h5 file from optistruct).

Hi Julian,
If you want to integrate a Multiscale Material Model, into an Optistruct simulation you need to do the following steps:
1. Create an Assign Card of type "MATMDS" and give it a "Name". Browse the for multiscale material file. This can be found in the the MultiscaleDesigner directory where all your custom materials are. Go to the folder of the material you want to implement in Optistruct and go in the "Mechanical" folder. There select the "_mdsMAT.dat"file.
2. Now create a new material in Optistruct with the Card Image set to "MATMDS". In the AMAT field, add the "Name" which was assinged in the first step (Assign Card).
Now you have successfully imported the multiscale material card into Optisturct and you can use it in your model.
