Re: [Yade-users] [Question #658699]: Deleting the desired interactions
Question #658699 on Yade changed: https://answers.launchpad.net/yade/+question/658699 Jérôme Duriez proposed the following answer: Hello, YADE is a very good computer program in the sense it always does what you're asking him to do (as every computer program..). I'd thus advice - to check your test (if it is properly written, it will run and the interaction will be deleted) - to check whether your interaction is not re-created just (one step..) after it has been deleted - to consider whether you could just zero the cohesive properties of these interactions (instead of erasing the interaction altogether), cancelling e.g. i.phys.FnMax and FsMax [*] assumping a interaction physics of JCFpmPhys type.
