How to impose a pressure load condition on interior nodes of domain?

I am solving a geometrically non-linear problem in solid mechanics using FEM. I want to impose a Neumann type pressure load condition on the interior nodes of my domain/ mesh (not on boundary)....

In axisymmetric (2.5D) solids for a finite strain elasticity problem, would the resulting 2.5D problem be a plane stress or plane strain problem?

For a nonlinear material model undergoing finite deformation, when considering the 2.5 D model about the axis of symmetry, would the stress or strains follow a plane stress or plane strain theory?...

Accounting for the circumferential strain in an axisymmetric formulation for finite strain elasticity?

For a finite strain elasticity problem using axisymmetric formulation, from the FEM modelling we have a solution for the displacement [ u_r, u_z ] from which one can compute the 2*2 Green-Lagrange...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

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...

How do I determine the degree of polymerization of PEG 400 based on NMR integration?

Hello, I am working on the photocatalytic degradation of PEG 400. I would like to know if it's possible to determine the degree on polymerization based on NMR integration, or by the MW of the...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

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...
