Having trouble getting seemly a fairly simple analysis to converge. I am tightening a call joint between two surfaces and have both surf to sur contact and surf gluing contacts.
The problem I have is that I want to first perform the bolt pull down ( 55KN ) acial load for a M14 bolt and than apply and non linear load (Table) that ramps from zerp to 37K back down to zero.
This solutions solves no problem using TLA-S solver however it does not tak einto consideration the table load and onyl applies the full load. I am interested in ramping the load back down to zero to see any permananet set.
When I try the ATS solver it all falls apart. I have tried various combonations of load steps and parmaetr changes. I even set up a series of spring to hold the ball jont in suspension until the contact surfaces can grab.
Tried different boltsteps, etc. Any suggestions on how to get a non linear laod to wokr with the TLA-S solver and be able to show the laod ramp back down to zero.
The settings used by the TLA-S method are documented in section 6.2.5 of the Advanced Nonlinear Theory and Modeling Guide
You can configure an ATS solution to use the same stabilization methods while allowing the load to ramp per the table data.
