Tosca

Efficient Optimization Based on FEA and CFD Simulations

What’s New for Tosca Structure 2019x and Tosca Fluid 2019

Tosca Structure

  • Tosca Structure.topology
    • Faster execution using shared memory parallelization (SMP) for topology optimization using shared memory parallelization. 
    • Enhanced topology optimization sensitivity filtering
      • Sensitivity filters has been enhanced and especially in combination with stress constraints or symmetry constraints are results much improved.
    • Enhanced optimizer for sensitivity based optimizations
      • New implementation of the internal optimizer, Convex Separable Approximation (CSA). The optimizer is now default.
    • Improved controls for overhang constraints for additive manufacturing
  • Tosca Structure.shape
    • Enabling sensitivity based shape optimization with Abaqus non-linear analysis
      • Non-linear static analysis 
      • (NLGEOM=YES, *PLASTIC, *CONTACT ...)
      • Including all modeling non-linearities as large deformations, contact and non-linear materials. 
      • Stress constraints
      • Reaction force constraints, even on *COUPLING elements
      • 2D and 3D elements
      • Abaqus execution in MPI-mode
      • Better performance, especially for stress constraints
    • Enhanced manufacturing constraints for sensitivity based shape optimization supporting the following manufacturing constraints
      • Plane symmetry
      • Cyclic rotational symmetry
      • Cyclic plane symmetry
      • Stamping
