Wisawanart 1 Report post Posted May 9, 2018 Hi I've been trying to set up the drop test tower simulation comprising of 8 components. All of the components are SOLID, I have faced with the difficulty to connect those components appropriately then, I decided to use the interface type 2 as the connectors. As a result, during running RADIOSS, it showed up the 10 warnings as below. 1. How to set this kind of interface with the suitable connection (Which parameter ?), just connect them instead of being the equivalent node. 2. I defined the BC as Solid symmetry and based fix, both of them cause the incompatible kinematic condition, how to solve?

Guest Report post Posted May 9, 2018 Hi, For tied contact use a slave node set and master surface instead of using surfaces and both master and slave and check if that helps. Quote Share this post Link to post Share on other sites
Wisawanart 1 Report post Posted May 9, 2018 Hi As the previous figure, I used slave node and master surface (Node to Surface) for all of the contact pairs. Best regards Quote Share this post Link to post Share on other sites
gopal_rathore 38 Report post Posted May 10, 2018 hi, You can run new model checker of hypercrash to identify the warning part. Also are you using IIgnore:1 in type 2 parameter, this will remove slave node not projecting on contact surface, this can also be displayed a warning If you have run the model and is it running fine ? I meant are you getting appropriate results with it Quote Share this post Link to post Share on other sites
