Optimization run continues.

Please contact MSC Apex Support.

W244ff728

Cannot map voxel …

The loads and boundary conditions could not be mapped to the voxel model and might not be considered in the optimisation anymore. LBCs should always be applied to Non-Design Spaces. These ensure a correct consideration of the LBCs during the optimisation.

W6f682328

Cannot copy output file. … does not exist as regular file

...

Time estimation has become inconsistent, expect inaccuracies.

For Restarts and Two-Stage Optimisations the time estimation is inaccurat.

...

There are two possible reasons for this warning:

  1. The available memory cannot be detected because of the operating system.

  2. There isn’t even enough memory available to let the optimisation start.

Make sure that there is more memory available or reduce the complexity.

...

Retained volumes occupy a significant portion of design space … volume 50% which increases the calculation time as well as the needed memory. Please reduce the complexity to reduce the calculation time and memory. Retained volumes will occupy about … GB of memory with current settings.

...

Unable to compute centroid for geometry … using bounding box center instead

A “corrupt” STL/PLY file was supplied for a Mask named in the warning text. Depending on other mask settings (whether the surface is to be used / filled), different centroids / centers of gravity are computed. This warning indicates all those attempts have failed and instead the bounding box center is used.

This can happen if the input has degenerate triangles or is not a closed surface. Please check the input files or replace these if possible.

Config entry 'calculationType' is deprecated, please use 'shapeQuality' instead.

...

This might occur while performing a Command Line optimisation. The defined build space geometry is not defined as the design geometry. Therefore, the geometry needed for the intersection is not available and thus no intersection geometry is available. Please adjust the Configuration File.

Geometry … is not used by anything

This might occur while performing a Command Line optimisation. A geometry is not used in the optimisation. Please adjust the Configuration File.

Failure criterion … is not used by anything

This might occur while performing a Command Line optimisation. The Failure Criterion is not used in the optimisation. Please adjust the Configuration File.

This Error is only produced after another Error was encountered. The optimisation algorithm tried to continue despite the previous Error but could not continue. The optimisation fails with this Error although the primary Error is the reason for the terminated optimisation.

The optimisation will continue to run with the changes mentioned above. If these changes are not representing the model set up you anticipated, please adjust your model set up in the “Keep Non-Design Spaces” panel.

W5acd8220

Some events are missing fixations.

Adjust your model set up so that every Event has fixations in all three main directions (or local coordinate systems main direction) included.

Eb20f3415

boundary condition is missing elements

A Non-Design Space was removed and the applied boundary conditions are not considered

The Design Space has lost the connection to the force/constraint application point. The model is no longer complete and it doesn’t make sense to continue with the optimisation.

Make sure that the Keep Non Design function is activated. Increase the Complexity or increase the Safety Factor.

Eb20f3980

Missing config entry …

The configuration file is missing an entry or command. Please check your entries in the Advanced User Settings or if you are using the Command Line Optimisation please check the Configuration File. You can find all commands for the Advanced User Settings here and the Configuration File here.

E0d03bf38

Unable to resolve input file name statistics.csv

This may occur if an optimisation is started with Advanced User Settings with which only 1 or 2 iterations should be calculated. If this is the case please add the following Advanced User Settings commands:

schedule.level.3.subiterations.~.outputMode.OutputGeneratedSurface

...

One of the result files cannot be written. This can happen while using parallelization (default). This can be resolved by adding following Advanced User Settings commands:

process.workers = 1

...

There are no privileges to access a file which is needed. Please check where the project folder is placed in which all the results are written. Network drives and cloud storage (e.g. OneDrive) are not recommended.
