Problem with visualisation without background

[polak7]

I have problem with a results visualisation:

Here is a print screen from my results:

The white line in the middle of the specimen is the problem. I do not want to have it there.

Now, look at the same results but with background:

There is also white line, but it is less visible. It means, that the background color have an influence on the middle area of the specimen. But it shouldn't.
I don't want to have background.
Is there a way to get rid of that white color in the middle of the specimen?

Sure.
Here is the first figure:

And the second one:

there is a particular kind of element in the middle of the specimen? Such as cohesive layers etc. ?

 

[polak7]

No, all elements are C3D8T type.
The specimen is build from two parts. It is a multilayered material. The contact between these two parts is defined by the friction coefficient.
So, after the compression process, the outer sides disconnect and a space arise between two layers of this specimen.

The following figure represents this phenomenon:

There is a gap on the right side of the specimen. It is correct. But there should not be the white color on the left, at the interface of that two layers. There is no space there from that point of view.

 

[OrlandoTaddeo87]

do you mean the very thin white line in the upper side of the gap?

 

[polak7]

Yes, exactly.
It can not represent the white background, because there is no background. There is the inner part of the material.

Have you set the white background by yourself or did you used the no background-option when "printing" an image file?

 

[polak7]

Sorry for my late answer.
Mustaine, I have used the no background-option, but when I set the white background and print with it, the result is the same.
