Hexahedral mesh problem (?) regarding flow past I-beam

Hello everyone, I'm simulating a 2D flow past a I-beam using k-omega SST turbulence model and I'm having some trouble with the mesh (I guess). I've managed to get a solution with periodic vortex...

Why do academics appear unconcerned that the physics for flying, sailing, and swimming are unexplained by scientific proof?

The media occasionally comment on the lack of evidence for any theory for how things fly, sail and swim (see attached file). The prevailing unproven theories for these activities are based on...

The most suitable method to calculate the stress intensity factor in the presence of contact between the crack lips?

I'm trying to study cracked structures under a compressive load taking into account contact between the crack lips. I would like to know if the method of extrapolation by displacement remains...

Which software is the best to model a non-linear concrete (ABAQUS, ANSYS,ADINA, ATENA, etc.)?

What is the best finite element modeling software packages for modeling non-linear and fracture analysis of CONCRETE? I've had some with ABAQUS standart/explicit, but I would like to learn if...

Do we need to keep looking for the fracture angle after the Puck's failure initiation is reached?

Greetings to everyone, Our team is currently working on the development of a VUMAT code in Abaqus for composite modelling using the Puck's failure theory as damage initiation criteria. Currently...

Fracture energy of concrete at sub-zero temperatures?

Both tensile and compressive strengths of concrete increase with the decrease in temperature. With this in mind and considering that fracture energy is in direct correlation with the so-called...

Permeability of fractured reservoirs?

Hi all, What I know the permeability of matrix and fracture can be in a broad range in fractured reservoirs. Am looking for the most usual range for their permeability separately. I will be highly...

Crack definition at symmetry plane?

How to define a crack at symmetry plane? Is it right idea? Crack seam we cant specify at symmetry edge (As crack seam can be specified at interior face of 2D). How to handle this type of...

How to change material in ANSYS & perform brittle deformation ?

I am currently working on a model for fracture generation due to pressure applied in ANSYS. When I am working with structural steel material it is showing only folding not any fracture initiation...
