Need a help with TACSBuilder in MPhys

[MohdAhmet]

I am working on a structural optimization project for a grillage model (bulk carrier hatch cover) using TACS with OpenMDAO. The objective is to minimize mass while satisfying yield stress and deflection constraints. I closely followed the example scripts provided in the TACS documentation as follows:
Initialize TACS builder

class PlateModel(Multipoint):
def setup(self):
struct_builder = TacsBuilder(
mesh_file=bdf_file,
assembler_setup=None,
element_callback=elem_callback,
problem_setup=problem_setup
)
struct_builder.initialize(self.comm)

but encountered the following error during execution:

Opt.py", line 62, in
struct_builder = TacsBuilder(
TypeError: init() got an unexpected keyword argument 'mesh_file'
mdolabuser@d007da2d526e:~/repos/tacs/examples/SCB/GrillageOpt$

My model is fully defined in the .dat file and verified independantly as well before trying to run the optimization.
The assembler is initilaized without arguments for this reason.

could you please suggest what is the best course of action? I have been reseaching for one week in the documentation to solve this error but I couldn't

Hi @MohdAhmet it sounds like you're using an out of date TACS version, please update to version 3.5.0 or higher.

Hi @MohdAhmet , like Tim says, the TACS version in our docker images is pretty out of date at the moment. I just opened a PR in our internal repo to update the TACS version the images use, if all goes well we could have new images out in a few days, but I can't guarantee that.

In the meantime, you could try checking out the latest version of TACS and rebuilding it, to do this you can go into ~/repos/tacs and run:

git checkout v3.7.2
make clean
make
make interface

You might have to setup your git credentials in the docker image to be able to do the checkout.

Ok, this is nice, I will try my best installing the newest version and let you know in case of any complications in the issues section.
Thanks a lot for your help

@MohdAhmet , we updated all our docker images to run TACS v3.7.2, the new images get built and pushed to dockerhub overnight so they should be available tomorrow.

That's really nice, thank you so much, I'll try to pull the new image tommorow

I have succesfully pulled the new image, thank you very much for your cooperation, Truely appreciated
