I calculate the pressure in some discrete points along a complicated geometry curve. The combination of the following tools brings me the pressure values.
1) Edge_3D (which is selected from the Data_Sets node) and
2) Line Integration (selected from the Derived_Values node) .
Concerning these values along the curve, I would like to project the corresponding points on a 2D plane, so that I can measure the horizontal distance between the points and the start. So far, I am only aware of the curve length till the point at which the corresponding pressure value is located.
Which COMSOL tool fits better?
Could it be useful to use one of the following Component Couplings?
General Extrusion,
Linear Extrusion,
Boundary Similarity,
Identity Mapping,
General Projection,
Linear Projection
If so, which does belong better to the occasion?
P.S. Is there an alternative way to do this?
Thank you in advance!
Hi,
Why don't you define a Cut Plane at the coordinates you need on your original geometry and have COMSOL plot it as a 2D plot?
Perhaps this helps: https://www.comsol.com/blogs/analyze-simulation-results-projection-operators/
@ Saif Manji
Thank you for your advice!
I make the Cut Plane on x-z surface as it seems in Fig. 1. In the next step I create a 2D Plot, so that I can project the points x1, x2, x3 on x-y plane (namely x1’, x2’, x3’).
How can I project these points x1, x2, x3 to bring me the distances x1', x2', x3'?
P.S. x1, x2, x3 are available so I can use them.
@ René Christensen, thank you for your advice! I preferred to bypass Component Couplings due to the short Documentation.
You are most welcome!
I believe René's suggestion is exactly what you need but anyways, my idea is to add a 2D Plot Group/Surface, set the Data Set to Cut Plane, plot and then measure the distance between any two points you want.
You can use Plotdidigitizer (a very handy free tool) to measure the distance accurately.
Good luck
