Structural simulation of a mechanical part

A non-transitory computer readable storage medium having recorded thereon a computer program comprising instructions for performing a method of B-rep processing for performing structural simulation of a mechanical part, the method comprising:

• obtaining:
• a first B-rep forming a solid representing the mechanical part, and
• a predetermined thickness threshold;
• and
• constructing, based on the first B-rep, a second B-rep forming a non-manifold object representing the mechanical part, the constructing including:
• identifying one or more thin regions of the first B-rep, each thin region having a thickness smaller than the predetermined thickness threshold, and
• computing, for each identified thin region, a respective mid-surface of the identified thin region, and replacing the Identified thin region by the respective mid-surface.

A computer comprising:

• a processor coupled to a memory and a graphical user-interface, the memory having recorded thereon a computer program comprising Instructions for performing structural simulation of a mechanical part that when executed by the processor causes the processor to be configured to:
• obtain:
• a first B-rep forming a solid representing the mechanical part, and
• a predetermined thickness threshold;
• and
• construct, based on the first B-rep, a second B-rep forming a non-manifold object representing the mechanical part,
• wherein the processor is further configured to construct the second B-rep by being configured to:
• identify one or more thin regions of the first B-rep, each thin region having a thickness smaller than the predetermined thickness threshold, and
• compute, for each identified thin region, a respective mid-surface of the identified thin region, and replacing the identified thin region by the respective mid-surface.
