Helllo all,
I'll post two different questions in a same thread.
-----------------------------------------------------------------------------
Question 1
I have made several fastener connections in a model, through spider RBE3s and the fastener represented by a RBE2. I leave an image so you...
Hello,
I hope you are doing well.
I have some questions concerning HEX mesh. My idea is to mesh a pin with HEX elements. I divided the fairly simple geometry into three cylinders, so it can be easily HEX meshed (without using the HEXMesh Bodies feature of FEMAP). I'll leave an image of the...
Hello,
I am using RBE2 elements to represent bolts that link three plates together.
The dependent node is in the top plate (where the load comes from) and the other two dependent nodes is one in each one of the bottom plates.
I leave an image below so it is easier to understand.
I have...
Hello,
I am analyzing a structure that it's going to be transported by road and by airplane.
Following standards we saw that normally for these transports the structure shall support at maximum 2.2g in all directions.
Hence, the structure was designed to withstand up to 3g (4g in best-case...
Hello all,
Quick and stupid question : Why FEMAP has such awful colors ? Besides that, does anyone know a way to modify the color of the borders of the elements ? Because, as you can see in the image below, I select a blue color for the elements but FEMAP says "okay, I am gonna put an AWFUL...
Hello,
I would like to start a discussion about the best way (mesh quality vs number of elements vs results accuracy) to mesh a large plate with a lot of small holes.
The thing is that I have a large plate (2000 [mm] x 1350 [mm]) which contains a lot of small holes (diameter 3.2 [mm], see...
Hello,
I hope you are well.
In the model I'm working with, I have to simulate a plate that rests over some rollers. Then, I want to simulate the rollers as constraints that only block the displacement in one sense for a given direction, i.e., for -Z the movement is constrained, but for +Z the...
Hello,
I hope you are doing well.
I am doing a burst analysis of a vessel. Consequently, NL material has to be introduced. Hence, I introduced the stress-strain curve and selected the Plasticity NL option. I followed what the NX Nastran's manual says :
The first point of the curve is (0,0)...
Hello,
I hope you are doing well.
On one hand (Symmetry BCs in presured vessel) :
I have been strugling for a while, thinking about the proper way to define the symmetry conditions for the model I am studying.
It is a simple pressured vessel, then, as it is symmetrical, I am analyzing a...
Hello,
I hope you are doing well.
I am analyzing a tank, and the idea is to simulate a burst test. Below I leave an image of the tank.
The thing is that I would like to study it as if it was floating in the space, i.e., analyze only the pressure and neglect the effect of the necessary...
Hello,
I hope you are doing well.
I started using FEMAP a couple months ago. Before I used HyperMesh as pre-processor.
I am doing some geometry cleanup, more precisely, removing a hole. The problem is that the hole was in the intersection of two surfaces (a fillet). Consequently, when I tried...
