I'm new to continuum mechanics and cannot find a good theory for large in-plane deformations of a homogeneous shell that allows for the plate to rotate.
use co-rotational formulation

I have seen evidence of a lower limit of this equation, but want to determine the resistivity of a composite semiconductor that has a cross section on the order of 100's mm^2 and about 100 mm in...

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

Actually, I am running cfd simulation for a heat exchanger which has two fluids one hot and other one is cold fluid. there is a solid domain between them, which I removed and instead I have used...

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...

We are trying to run fiber photometry experiments for long time scales, but we get these sinusoidal artifacts that come up. We think they may be caused by twisting of the fiber optic subject...

Hello, I have used the shell function on SpaceClaim to create thin solids for the model I am studying. These are contained within an enclosure for my study. I chose this approach as it avoids the...

No streamlines present means whether the flow is getting obstructed there and the velocity inside the region is zero? Or else, the fluid is trapped inside that region with a nonzero velocity?...

Hello All! I'm trying to model a contact between a coated substrate and a tip in Abaqus. The coating is ultra-thin compared to the geometry of the substrate. So I defined the coating using the...
