Hi everyone,
I imported a geometry which is composed by surfaces objects with x thickness (picture on the left ). I want to add a volume in the bottom of the structure like in the picture on the right. Do you have any ideas please. Thank you...
Hello,
I'm doing some tutorials to learn how to simulate a seismic response of a reactor. I modeled at first the reactor and did the static and modal analysis and it gives me as eigenvalues 10Hz , 14Hz, 20Hz,... 68Hz. Then Iwanted to integrate the basemat of superstructure and eigen values...
Hello community,
I want to formulate a data-driven calibration model between physics and simulation results. I have an a model encapsulated in an executable program (data_generator.py) that for a load 𝑃 located at 𝑦 = 𝐿, generate 𝑁𝐵 random beam widths 𝑏(𝑥) and computed the beam displacement 𝑤(𝑥)...
Hello,
Anyone can understand the passage from line 16 to line 17 please ?https://files.engineering.com/getfile.aspx?folder=3dc34337-93f9-4155-a60c-66de021a9724&file=leading_order.JPG
Hello ,
I want to model the of power electronic device interconnections using thermal-electrical modelling.
Any ideas please about the steps in general that I should make and What software should I use ?
Thanks
Hello,
I am coding the truss problem by finite element (figure below).I found difficulties at the level of the assembly of the stiffness matrices . Since the beams do not have the same materials, we will not have the same stiffness matrices. In the program , how to do the loop of assembly ? Any...
Hi,
I keep getting this error about my problem essentially being too complex for the student software to allow it to be solved. I have a support which contains a tube in which I applied 3 forces and a moment. Even when I use The mesh size it doesn"t run and it keeps showing me same error. any...
Hi,
I modeled a circular crack in a parallelepiped how I know that my mesh is good in a fracture model, I could not understand the curves of the stress intensity factors and the integral j as a function of l 'curvilinear...

Hello everyone,
I want to study the contact between the cylinder and those rigid bodies. I impose displacement u = -30 m/s to the nodes of cylinder and I want to see contact forces.
I didn't understand what contact forces (contact reaction) means ? is it the forces (on "y" direction) in the...
Hello,
I want to model an hyperelastic cylindrical tube (with mooney rivlin law). we apply to this tube a displacement as shown the figure below.
I want to know can I just model the superior part ( I mean can I consider it symmetrical problem ?) . If so, should I change the value of displacement...
Hello ,
anyone knows how to do such a much in a circle (2D plane strain) on APDL please ?

Hello , can anyone please tell me what is the difference between compressible and weakly compressible flow in term of equations ?
Both have ∂ρ/∂t + ρ∇u = 0
Hello ,
For a turbulent flow ,to determine the nusselt number.. anyone knows how to calculate the fluid viscosity at the bulk fluid temperature and the fluid viscosity at the heat-transfer boundary surface temperature , please...
Hello,
I put a piece in an oven.
can I impose boundary conditions of the room and see the evolution of temperature on the surface of the piece ?
can I do that in COMSOL ?
hello, we bake aeronautical pieces in an oven.
the piece ( prepreg + nomex ) being in the mold, we put it inside the oven.
a thermocouple is linked to the surface of the mold.
a temperature profile is applied to the oven chamber (ramp up, holding, ramp down).
I want to make a thermal simulation...
