Re: WF4 MDX animation of a "Roll-Up Window Blind"
Something like this? The spiral datum curve is the Ground body; the "lever" is the Motor; and the puck uses 2 Slot constraints and a Planar constraint. This just happened to be what I was working on...

Antonius, thanks. My model already used the same connection types as shown in the You Tube video (some different references). Good to know the datum points have to be separate features. My were already...

Re: MDX Linked Chain Model
I took a careful look at your model and I am not surprised it went a bit nuts. I'm going to recommend you simplify the references. The 1st few links do not have a pin connection. One is cylinder and...

Thanks, I will do that. I did not know about the cylinder vs axis benfits. Right now I'm working with just 5 links with one of them with an attached lever that has a slot-follower. I'm not sure how I...

As I will gladly admit, I am no expert at MDX but I know how to make the system work for me if I give it a good nights rest. Not knowing if it is directly possible, you could think of making a linear...

View ArticleWhat's the relationship between p-level, solution time, mesh & accuracy?
First some perspective: I deal with very large structural (rocket) problems, so for solution time (lots of optimizations) I am highly incented to use single-pass analyses rather than multi-pass. So...

Hi Chauncey, An interesting question! First off, congratulations on getting a 4-parameter optimization study to run. I've yet to have success with even a 2-parameter study - I just get stuck with...
View ArticleRe: What's the relationship between p-level, solution time, mesh & accuracy?
Thanks for the response. For what it's worth, since WF5 I routinely optmize on upto 9 parameters generally using a failure_index<1.0 optimization criteria. I do find "9" taking painfully long,...

Two other quick thoughts: 1) I presume you've already increased SOLRAM (the memory allocation in the Options dialog box) from the default 128 MB? 4-8 GB might be a better first guess. 2) In case you...
View ArticleRe: What's the relationship between p-level, solution time, mesh & accuracy?
Hi Chauncey, I agree that if your p-levels remain below 9 during an single pass adaptive (SPA) analysis, then the solution is reasonably numerically accurate. Of course, it's impossible to make...

Is there a neat way in Mechanica to run a series of analyses iterating a parameter (so a sensitivity study, so far) and then to set up an identical results view for each value of the parameter and...

I've done it yesterday using.... powerpoint You can create a result template and use it for each "iteration", exporting the resut window as a jpeg picture and inserting them into a powerpoint...
View ArticleRe: Animating in Mechanica
Lateral thinking - I like it! Is a "result template" different to a saved results window (.rwd)? And are you just manually updating the parameter and re-running the analysis each time?
View ArticleRe: Animating in Mechanica
A result window belongs to an analysis results, then you have to overwrite each of your "iteration" by running the same analysis several times. With a result template, you can create (or rename in...
