Hello, I want to say sorry in advanced for my first post being a question, but it seems that I have hit a roadblock that I can't overcome by myself. My problem is as follows, I am trying to model a liquid going through a solid with these specific properties.
The solid properties are:
Density: 1160 kg/m3
Poisson's Ratio: .5
Youngs Modulus: .2 MPa

The liquid properties are thous given by default, H2O in this case.

Setting and Physics:
Tools
• Motions- Right-click to create “New”- “Morphing”
• Motions- Right-click to create “New”- “Solid Displacement”
Continua
• Mesh 1- Check “Per-Region Meshing”
• Physics 1 (liquid)- Models
o Constant Density
o Gradients
o Implicit Unsteady
o Laminar
o Liquid
 Set characteristics of blood
o Segregated Flow
o Three Dimensional
• Physics 2 (solid)- Models
o Constant Density
o Gradients
o Implicit Unsteady
o Linear Isotropic Elastic
o Solid
 Set characteristics of Solid
o Solid Stress
o Three Dimensional
Regions
• Be sure that the interface is set for all boundaries from solid to liquid
• Regions- Inner_Part_Indentations- Properties Window
o Set Physics Continuum to “Physics 1”
• Regions- Inner_Part_Indentations- Physics Values
o Motion Specification- Set Motion to “Morphing”
• Regions- Shell_Part_Indentations- Physics Values
o Motion Specification- Set Motion to “Solid Displacement”
Stopping Criteria
• Maximum Inner Iterations- 20
• Maximum Physical Time- 1 sec
• Maximum Steps- 20021

My problem stems from the fact that I can run this with no problem when my solid properties are of those of any metal or even the rubber material found within the program. I believe the young modulus is set very low for this specific analysis. If anyone has some hints, solutions, theories or background information I would really appreciate it. I appreciate your time in advance. I forgot to mention I am trying to model displacement of my solid cylinder. My cylinder has a radius of 4mm for the fluid region and 4.8mm for the shell region.

Thanks again,

Richard

Are the displacements you expect still in the linear elastic region of the solid? Otherwise the FVS model should not be used.
