Thank you, Blas. I think this feature can be helpful. It requires a little bit different logic: instead of renumbering of the model after the import, numbering scheme is ensured during (or to be precise right before) the merge. It however does not solve the problem of re-arranging of the...
Of course, explicit assigning of the OFFSET is a rather logical way. It is however a manual operation. This procedure can be improved in the following way: for all visible layers, renumber elements/nodes using layer ID as the OFFSET (as explained in the first post). It can be implemented as a...
I see your point. The problem is that very often in space industry there is a requirement for the numbering range of the sub-assemblies. Numbering range philosophy also comes in handy when performing calculations based on the FEM results, for example bolt verification for the complete structure...
Thank you, Blas. I am already looking forward to the next version!
I also use Layers as the basis for the model organization in FEMAP. It is indeed the most intuitive way.
By the way could you recommend any existing solutions for the model renumbering based on Layer' information (e.g. layer ID)?
well, JPL somehow managed to use FEMAP for their projects (case study). I am pretty sure that complexity level there is very high as well.
Anyway, thanks for the feedback. Can you recommend something regarding the API?
That’s an example model from HyperMesh tutorial;) In my working model I usually have about 5000 components, about 20 large assemblies with 10-15 sub-assemblies each. A sub-assembly can have a sub-sub-assemblies as well. Think of a spacecraft: structure - system - sub-system -...
Currently I am using HyperMesh and model organization looks like it is shown in the figure attached. I am trying to come up with a similar approach in FEMAP.
Super-elements is not an issue in fact: plotel elements are imported into the Preprocessor and matrix (*.pch, *.op4) and assembly...
rb1957, thanks for the reply.
By assemblies I meant a set of components grouped together in FEMAP itself. Typical example is a model with more than thousand parts which can be represented as physical models or super-elements, e.g. complete assembly of a car, spacecraft or a ship. Flat hierarchy...
Dear community members,
I am trying to adapt the existing model organization approach from HyperMesh to the FEMAP environment, and I would be glad to hear your feedback and suggestions.
1. General organization. According to the existing model organization approach, model entities (nodes...
Hello all,
I am interested in implementation of the co-called Segalman-Reese method for RMS von Mises stress calculation (see paper attached). This method employs modal behavior information allowing reduction of the computational cost. There are several commercial solvers like ANSYS, Altair...
Dear all,
I generate reduced stiffness matrix and a load vector using *SUBSTRUCTURE GENERATE (the while code is presented below) card and afterwords I do some operations in matlab.
In order to validate the stiffness matrix and the load vector I made a simple test: idea is to compare nodal...
