Electronic cooling simulation using OpenFOAM
Space limitations and high power supply ultimately lead to innovativ cooling design for a wide range of PCB. The arrangement of the power supply’s, heat sink dimensions and design of the outer housing become more important. Thermal simulations within in the design process of PCB help to overcome overheating problems in the later production stage. …

Degassing simulation using OpenFOAM
Space limitations and high cost pressure ultimately lead to hydraulic tanks becoming increasingly complex and smaller. This leads to a dramatic reduction in air separation in the tank – and thus to an increased amount of free air in the hydraulic system. In hydraulic systems, free air is still a technical challenge today. As long…

Vector Calculus in Bash Scripts
When performing preparatory operations for e.g. CFD or FEM analyses, it is often necessary to specify vector parameters. Vector constants are easy to handle: DIR=“1 0 0″ myMesh –direction „$DIR“ However, it quickly becomes complicated if the vectors have to be manipulated, e.g. multiplied by scalars or rotated. A powerful solution is to use the…

Exporting a STEP file with named surfaces from PTC Creo
When preparing geometry for numerical simulations, it is often required to mark individual surfaces in the model. These surfaces can then be used e.g. as an inlet or forces and pressures can be applied in a structural simulation. The STEP format supports named entities. The question is: how to set the names in the CAD…
