Hello to everybody,
I am a bit confused about the calculation of an OSPL of a pressure spectrum.
From what I learned, I know that the OSPL should be a number describing how much energy is related to the spectrum under consideration. Nothing special so far, but I read about two formulas for its...
Hello to everyone,
I am having problems with a eigenvalues analysis. In particular I need to extract the acoustic modes from my model.
I have created a fluid material (mat10), specifying all the properties needed, but when I run the analysis the following fatal error appears:
*** USER FATAL...
Hi guys,
My part consists of an airbox for automotive applications and I need to get the air volume inside it which, of course, is not present as body. Does anyone know a simple way to obtain such an air volume as a body (starting from the airbox)?
I have attached an image of the airbox...
Hello to everyone,
As in the thread below, I do not succeed in exporting a solid object in a step file, namely when I try to import it in another program the exported .stp file contains only surfaces.
Is there anything I have to check before performing the export operation?
Thank you for your...
Hello to everyone,
I have a problem in importing a geometry from Siemens NX to FEMAP. In particular my CAD is constituted by an assembly.
First, if I try to import the .prt file directly from Siemens NX, no solids or sufaces are imported at all.
Then If I try to import in FEMAP environment a...
Hi to everyone,
I have to mesh a geometry and, before this, I want to "clean" my CAD model from things like words etc., in order to make easier to mesh it.
I have attached an image of my model in which there is a surface I want to delete and I wonder if an efficient method (that is not...
Hi to everyone,
I have a problem with the aspect ratio of some elements within my meshed geometry.
Practically I need to mesh a geometry with a max aspect ratio equal to 5, but, after many operations on my mesh, some elements still have a too high value of the aspect ratio.
Can someone...
Hello,
I have a problem in exporting a geometry I have created.
More precisely, I want to export my model in such a way that it appears as made of only one solid instead of all the boolean/extrusion operations.
Can someone help me with this issue?
Best regards.
Hello to everyone,
Is it possible in FEMAP 11 to extrapolate from a 3D element only one "surface" in order to obtain a 2D element to which it is possible to assign a plane element property?
Hi to everyone,
I am completely new to the use of FEMAP and, as in the subject, I am trying to perform a modal analysis of a two plies plate but I am having two fatal errors from NX nastran.
In particular, the setup of the analysis I have setted is the following:
1) To import the .IGS file of...
Hi to everyone,
I am quite new to the use of UG and I need some help.
Practically, I need to export in exel or text file the coordinates of some points which i have selected on an existing part.
Can anyone help me?
