new contact model

[xibaiw]

I referenced the contact input file from the test test/fullscale_tests/test_penalty_contact/penalty_contact_friction.yaml case to create my new input file, but the program reported this issue during calculation. Is this a bug? Follow is my input file.

Hi @xibaiw, the structure and the handling of the Contact section is currently in development, see #276. You can ignore those warnings ;)

The warnings are fixed in Version 1.4.3, should be released later this day.

It's working as expected. Keep in mind that we added this just recently, so there is no verification yet.

hello Mr.Hesse, I run the example disk_impact.yaml , the rusult seems very different from that by Peridigm. Meanwhile I modified the test Contact.yaml, in this time i added interblock damage1_2: 0 2_1: 0 instead of bond filter, the rusult is also different from the original setting(the bond filter one). Maybe there's something wrong with the contact model? Will it be a focus for the next few versions?

[JTHesse]

Yes, we are currently investigating the difference and optimizing our contact search algorithm. In the current PeriLab version we are only using the surface nodes as potential contact nodes, which isn't possible in Peridigm.

The new PeriLab version 1.4.5 fixed a few contact related issues.
