Pushover solver and Boat impact are not yet supported for shell elements

November 2, 2022

Resolved

None

Version 2023.04

Pushover and boat impact, including geometry nonlinearity and plasticity, are unsupported for shell elements with small strain behaviour.

Consider using a B-Bar for thermal expansion training.

We want to use B-bar for thermal expansion training by default because we are using B-Bar for FEA by default.

Currently, inconsistent integration types between FEA and training lead to significant error indicators for some models.

Normal load defined by elem_xyz no longer works.

An Error message is returned when using elem_xyz for normal load:

----

A parameter was not assigned a value.(('o-normal_load_surface_200',) ('elem_xyz',))

----

Enable Heat and Elasticity solves.

Users need to have two separate collections for two different physics: heat and elasticity.

Maximum envelope solution for time-history simulation.

This feature still needs to be implemented for time-history solutions. It includes:

- Maximum envelope Von Mises stresses to check with Allowable Stresses.

- Minimum envelope in-plane (panel) stresses for shell buckling check.

Nonlinear shells (NGLEOM and/or plasticity) implementation are not finished yet.

They still need to be fully validated.

"Occlusions" in cavity radiation are not supported.

Currently, our ViewFactor matrix calculation ignores that some elements may not be able to "see" other elements due to occlusions in the geometry of the cavity.

Version 2023.04

Processing time and memory required for jacket simulations are reduced. More updates are in progress.

Using Single Response can push the performance of multiple-time-step solve. However, there are some limitations:

- It only works for static elasticity projects (for Floating Wind, Fixed Offshore Jacket assets)

- The solving time is not displayed on the right panel of Akselos Modeler when it finishes

The RB-FEA Solver for Thermal Physics may experience limitations when working with temperature profiles that exhibit significant variations.

June 1, 2023

Working on measurement

When dealing with large temperature profiles, we strongly recommend caution while using RB-FEA. It is advisable to carefully assess and validate the results obtained from the software in such cases.

We can develop a Machine Learning (ML) model to anticipate stress levels in certain situations. In such cases, detailed information regarding the ML specifications, testing methodology, and verification process are provided to clients.
