Test LLM-Powered Workflow Analyzer with Complex Invented Request

This test uses a realistic, complex optimization scenario combining:
- Multiple result types (stress, displacement, mass)
- Composite materials (PCOMP)
- Custom constraints
- Multi-objective optimization
- Post-processing calculations

First, I need to extract the maximum von Mises stress from solution 2 subcase 1, and also get the
maximum displacement in Y direction from the same subcase. Then I want to calculate the total mass
using the part expression called 'panel_total_mass' which accounts for all the PCOMP plies.

For my objective function, I want to minimize a weighted combination where stress contributes 70%
and displacement contributes 30%. The combined metric should be normalized by dividing stress by
200 MPa and displacement by 5 mm before applying the weights.

I also need a constraint: keep the displacement under 3.5 mm, and make sure the mass doesn't
increase by more than 10% compared to the baseline which is stored in the expression 'baseline_mass'.

For optimization, I want to vary the ply thicknesses of my PCOMP layup that have the suffix '_design'
in their ply IDs. I want to use Optuna with TPE sampler and run 150 trials.

Can you help me set this up?"""
