Hypermesh custom beam section with Sketches issue
Hi everyone, I am attempting to create CBEAM elements (Nastran) to represent some tubes which have an oval shape. The way I am doing it is by line meshing a line with CBEAMs and then assigning a PBEAM property which reference a beam section collector which references a beam section which I defined using a sketch. The…

In Feko, how do you change the nearfield plot scale unit in 3D or surface plots?
Hi, I want to show a nearfield result plane in the unit of dBuV. I can set it to dB, but then it only displays in dBV. I can set a field scale range, or I can set units for the x and y axes, but not for the field scale unit. The option that affects this change for Cartesian plots seems to be missing for surface or 3d…
