Plot Material Properties

[jb885]

Hi,

I am creating a fracture healing model using the FEBio software and it would be useful to display the elements material properties in PostView. Is there anyway of linking the material colour to the properties such as Young's Modulus? Or setting the properties as an output so it could be colour mapped.

If this isn't possible if anyone has any suggestions of post processing software that may be able to do this and read the FEBio plot file.

Thanks

Jack

Hi Jack,

You can output material properties to the plotfile from FEBio and then plot them as a contour plot in PostView. To do this, add the following to the plotfile section of the FEBio input file. (Assuming your material is named "Material1" and the parameter is called "E")

<var type="parameter['Material1.E']"/>

You can also provide an alias, which is the name for the field that will be displayed in PostView.

<var type="parameter['Material1.E']=E"/>

Note that this assumes that the material supports heterogeneous material parameters.

Please give this a try and let us know if it worked or not.

Cheers,

Steve

Hello Steve,

is this still the current way to output heterogeneous material parameters? I tried it, but unfortunately I didn't get it to work. I had a look at the user manual chapter 3.18.2.1 Plotfile Variables as well, but wasn't able to generate the output. I tried the following:
<var type="parameter['Material1.E']=E"/>
<var type="parameter['E_map']=E"/>
Is there something I'm missing?
I've attached the input file.

Thanks for your help

Hi Franziska,

Try the following:

<var type="parameter['fem.material[0].solid.E']=E"/>

That should do the trick.

Hi Steve,
yes, this worked perfectly Thank you!

Hello again,
is there also a way to plot parameters of a solid as part of a solid mixture inside a biphasic material? For example Young's modulus E in the example below?

<Material>
    <material id="1" name="Material1" type="biphasic">
        <phi0>0.5</phi0>
        <fluid_density>1.0e-10</fluid_density>
        <solid type="solid mixture">
            <density>2.0e-10</density>
            <solid type="neo-Hookean">
                <E>1.0</E>

Hi @Franzi,

Try adding this to your plotfile section:

            <var type="parameter['fem.material[0].solid.solid[0].E']=E"/>

Let me know if that worked or not.

Best,

Hi Steve,

thank you, it worked! I swear I thought I tried that before asking you again, but apparently not
Thanks again!

Hi Steve,

I want to plot the material properties. I have tried the following code for plot the heterogenous material properties of my model.

<var type="parameter['Materialname.E']=E"/>

Is there something I'm missing?
I've attached the input file.

Hi Subrata,

Try this:

<var type="parameter['fem.material[1].E']=E"/>

Also, please check out this appendix in the user manual, which talks about the syntax for referencing model parameters.

Best,

Steve
