Not a pure rotation
Hi,
I have tried the twisted bar and it does not what it should. I have compared yours and mine files and I found that the only difference is, that you have the contact and constraints defined in the step 1, but I have it in the initial one. However, I did everything as it is in the tutorial. Then happens, that the bar is not only twisting, but also tilt slightly (even there are the restraints for the rigid body in the x,y,z direction and the rotation Ry, Ry as well. Note I have the same coordinate system).
How do I define that all the boundary conditions, contact and constraints are define not in the initial step but in the step 01?

Billet problem - bulging of the side wall
Hi,
I have a question concerning the billet problem from the preview tutorial. When I define the rigid wall contact it is kind of an infinite plane, right? So how it is possible that the right side of my box bulged over this boundary? I attached the screen shot. Secondly, I know it is a basic mathematical stuff, but I just don´t see it right now – the equation for the plane with the coefficients a=0, b=1, c=0, d=-1 is then y-1=0. But doesn´t that mean that the plane intersects the y-axis at “1”? However, it is the bottom rigid wall, so it should be “-1”. Or I missed something?
Thanks

Hi Michala,
It is probably easier if you can send us your input files. Then we can take a look at them and see where the potential problem lies.

Hi Michala,
When I run the file you attached, I do see the bar twisting, so I'm not sure I understand what the problem is. Is the bar not twisting at all for you? Is it doing something else?

Ah, I see, it looks like tutorial 3 has changed slightly from our initial version. I'll see if I can fix that. In any case, if you move the center of mass of the rigid body to 3,0,0.5 and increase the rotation angle to 3.14 (if I remember correctly) you should get the same answer.

Hi,
I have done the first example( A simple tensile test) on Preview user manual and saved it as a preview file. How can i run it in FEBio and get the results ?. I export the preview file to FEbio format. Then tried to run it in FEbio,then what happens is command window appears and disappears instantly. I am not sure why?
Can someone please help. Thanks a lot.

Hi,
I am getting to know PreView, FEBio and PostView, so I'm going through the tutorials now.
Tutorial 6, the multi-step analysis, won't run for me: FATAL ERROR: Missing attribute "surface" of tag "surface_load" (line 929)
Please find attached my input file.
Thanks

Hi,
This was a bug in PreView. A new version of PreView is uploaded. Please try it and let us know if the problem is solved.
