View ArticleRe: Issues with Using Creo Simulate Fasteners with Through and Blind Holes?
Hi Charles, Thanks for confirming that Simulate fastener features do not work with drafted holes. That was kind of what I had determined with the testing I have done so far.Yes, the ground springs are...

Don, Minor point re ground spring ,,, it may be better to link adjacent parts with point to point springs back to a constrained part rather than parts to ground. 2 reasons - I know the ground spring is...

Hi Charles, Good points on the ground springs. Thank you very much for the insight! Don

Re: Weld Suppression?
John, Can you give a bit more detail with respect to how the contact and the perimeter weld cooperate? General comments - Perimeter welds - doublers; usuallyOnly shellsContacts don't work with shells...

Hi, A preloaded structure is the common starting point for many subsequent studies. Each subsequent study is a different loadcase. This is driven through a design study in this case but could...

Edge orders and timesteps
Hi, Following on from Unecessarily repeated first time step I have been investigating the use of timesteps rather than design studies. Question: If I ramp the load with the following histories and...

Re: Hose simulation like mechanism
It's possible to approximate this by creating a bunch of short "pieces" of hose that are connected to each other via a joint. If you want only 2d motion then use a pin joint. Otherwise you can use 6DOF...
View ArticleRe: ANSYS - Creo Simulate discrepancy
Quick check is not "that bad" really. It sets each element to P=3 so in theory is better than using linear or quadratic tets.... assuming the mesh is not too rough. *with quick check you are forcing...
View ArticleRe: Edge orders and force balance
Hi Steven, That is what I did. I was quite surprised that the solution doesn't settle down until order 3. Hence my question. Contact force in my model: Order 1 = 571NOrder 2 = 6296NOrder 3 = 7546N...

Thanks for that Roland, I think we probably do most of that Constraint reactions measures (moments and forces) are applied every time as part of a model build; I don't know why these are part of the...

Re: Non-symmetric results for symmetric model and load?
Hi all, Let me provide an update to the issue. In Creo Simulate, based on the component (solid or surface geometry) AutoGEM tries to create tetrahedral elements where applicable. This is the default...

Hi all, My apologize for take so long to provide an update. I will try to break this down into three topics.......as there are three items covered in this thread. 1) Enforced displacement, tangential...
View ArticleRe: Edge orders and force balance
Steven, The purpose of low order mesh was to study force balance without burning too much time. You are right,,,,, what happens at 4,5,6,7 ...? I stopped at 3 and pursued answers for a project; the...

Dear Mark Thank you very much for your detailed answer, but I'm afraid it is a typical case of: too little too late.It's taken your company 17 months to provide me with the answer that I need a finer...

Re: Non-symmetric results for symmetric model and load?
Hi, the cause of the problem is the wrong transfer of the geometry description to Simulate (beforeAutoGEM).Paul
