Linear Plate Solver

Diana Carlson Hi there Would you please help me to model the coupling of Navier-Stokes and linearplate equations? Especially the way of defining the pressure exerted by the fluid on the plate for 2 and 3 dimensional simulations in the sif file for linear plate solver, and the way of accounting for m...

Re: Inquiring displacement of a node

I tried too many possibilities (VariableGet, GetScalarLocalSolution, GetVectorLocalSolution, GetReal , .......) with different modifications in the SIF file, but none of them were successful and I'm not that expert to find the reason. I'm really sick and tired of this trial and error and will be ext...

Inquiring displacement of a node

Hi there I'm working on a user defined function I developed for using in a boundary condition segment. I need the displacement of a particular node (with global number of 3421) that does not belong to the target boundary associated to this UDF. How can I inquire displacement of this node? Thanks, Di...

‘Equation = Elasticity Solver’ or ‘Equation = "Stress Anal

Hi there I have some different questions listed below. - What is the difference between ‘Equation = Elasticity Solver’ and ‘Equation = "Stress Analysis"’? - Is it right that direct solver is better for Elasticity Solver and iterative solver for Stress Analysis? Thanks, Diana Carlson,

Rotation and interpolation

Diana Carlson Hi there Shown in the figure is the geometry of my problem which consists of two bodies. The blue circle is the internal boundary for body 1 and external boundary for body 2 (two boundaries are present there as I meshed body 1 and body 2 separately). Imagine both bodies are governed by...

multimesh test case

Hi there
First I want to appreciate for the multimesh test case added in Elmer. Then want to ask for a problem definition if available for this test case. Certainly it will help much in understanding and avoid misinterpreting the problem.

Thanks, Diana Carlson

Re: Interpolation of temperature between two overlapping meshes

Dear Peter I tried as many possibilities as I could have imagined but they didn't work. I think there is still something unclear for me. One of the "SIF' files I used is Header CHECK KEYWORDS Warn Mesh DB "." "GlobalMesh" End Simulation Coordinate System = Cartesian Simulation Type = Transient Stead...

Re: Interpolation of temperature between two overlapping meshes

Hi peter Actually my first problem is to require Elmer distinguish between mesh 'a' and 'b'. In other words both of meshes are defined in a single category of files (header, element, nodes, boundary) and I don't know for example how to define them as oldmesh and newmesh for InterpolateMeshToMesh. Th...

Interpolation of temperature between two overlapping meshes

Hi there Shown in the figure is the geometry of my problem which consists of two overlapping meshes. Appended in the figures is their respective body index and node number. I name the background mesh ‘a’ and the other one ‘b’. The conductive heat equation is the problem’s governing equation. I want ...
