Hi all.<\/div>\n
I’m calculating the simplest rubber model, a flat problem.<\/div>\n
The bottom bar must go 5 mm for the rubber to fit on it.<\/div>\n
In reality, everything works, tests have been carried out.<\/div>\n
<\/div>\n
 <\/div>\n
But the calculation is interrupted with an error and the mesh is distorted:<\/div>\n
<\/div>\n
<\/div>\n
 <\/div>\n
Contact with friction, I tried a hundred different settings and life hacks, adjusting the contact does not help.<\/div>\n
I also tried disabling errors using the NCNV,0 command.<\/div>\n
I tried different types of grid (triangle and quad) and also changed the type from linear and back.<\/div>\n
In general, I tried a lot of solutions to the problem, but this does not help. I also tried solving it in the transient module.<\/div>\n
The Ogden or Neohukean rubber model usually worked well.<\/div>\n
 <\/div>\n
The task always stops at 2.99 mm.<\/span><\/span> Then I did an experiment, took three steps.<\/span><\/span> 0s-0mm, 1s – 2.9 mm, 2s-2.9mm, 3s-5mm.<\/span><\/span> At the second step, the bar simply stood still at 2.9 mm, the error still appeared, but at the second step the grid was distorted.<\/span><\/span> This is weird.<\/span><\/span><\/span><\/div>\n
 <\/div>\n
Tell me what to do?<\/div>\n","protected":false},"template":"","class_list":["post-367228","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
