There is a large mast that is a few meters long. And then there is a little plate bolted onto the top of the mast.
I only want to simulate the plate on top of the mast. Is it possible to exclude the mast from the calculations ? The mast can be assumed as 100% rigid in this case. Calculating the plate takes only a few seconds, but it takes very long to calculate the whole mast every time.
So how can the mast be assumed as rigid, so that it isn't calculated every time I run the simiulation ?
If you want to analyze the plate, then just eliminate the mast altogether. Right? It looks like you have constraints on the four corners of the plate. If so, then does the lower part of the mast deflect? I do not see any other constraints.
