Subcase Manager information intransparent

Hello experts,

 

I've found in a thread of @Guddal 

 

Managing-large-number-of-load-cases-and-loads-in-Simcenter-3D/m-p/584751/highlight/true#M5223

 

that there is the chance to manipulate load magnitudes of global load case definitions. They can be modified with Subcase Manager or Subcase Association Manager (sounds great!!!)  - It's new for me.

 

By dealing with it there are two problems encountering.

First question:

Where can I see that definitions are made with Subcase Manager to configure global magnitude of loads in load cases? Neither the loadcase itself nor the solution dealing with the scaling factors for loads in loadcases have such an information (about Subcase Manager is ACTIVE!)  - Do I look for it at the wrong place? The only information about that are the Subcase Manager itself, and the Mechanical Load Summary of a specific load case. But, both information are only given after active "scanning" for it. And the Mechanical load Summary only provides the results without giving information WHY the native input loads don't summarize to global sum.

 

Second problem:

After cloning a solution I would assume and also insist that both solutions provide identical results. But, after cloning a solution having modifications in Subcase Manager those modifications get lost in new solution. All scaling factors are set to 1.000 (default)

Are these bugs or features? - Are these problems solved in higher versions of NX? - I use NX Simcenter 10.

 

Who can help? - Best wishes, Michael

Hello Experts,  addition:

 

In NX11 I could see that cloning keeps the scaling factors of loads in sub cases (or load cases):

The values are the same as in original Solution "Subcase Manager" (see thread above).

So, the only point is how to see that modifications are made in Subcase Association Manager?

Michael,

 

I recall running into the issue with cloning a solution and losing the scale factors defined in the subcase manager. I (and a few others) submitted PRs on it back in the NX 10 timeframe. Clone existed prior to subcase manager, and it didn't take into account the potential scale factors there. The PRs I'm viewing were closed as fixed in NX 11. If you are seeing otherwise in newer versions of the software, then please contact GTAC and raise an issue. My PR number was 7150743.

 

I see in your message that you are in NX 10, so I think we are going to have a positive response here for you.

 

Regards,

Mark

Hello Mark,

thank you for answering. Yes, it works fine in NX11 as  I already had checked before (see prior article in thread).

 

So, is it a hidden feature to manipulate scaling factors of load in this way? - I assume, no.

So Question, is there a GOOD way to MARK a solution when scaling factors of loads are modified in load cases? - I guess at that moment the user has to do it manually but which way would be a good one?

1. May be one could set a text fragment as indicator into solution name of simulation file...

2. Description of solution in Solution dialogue => General could be also a place to inform, but, I assume it can be overlooked easily.

 

A guess best way would be if NX itself brings that information into foreground:

- putting "Subcase Manager" as a permanent entry in object tree of solution.

- informing about scaling factor during process of "Mechanical load summary"

- using special icons for solutions with scaled load.

 

Maybe such a modification is already done in higher version of NX? (I use NX10 and can monitor NX11.)

What do you think or know? - With kind regards, best wishes, Michael

Michael,

 

You raise very good points about the lack of feedback regarding the load scale factors defined in the subcase manager. Mechanical load summary does take them into account, but it doesn't mention the scale factors. Nor could I find anywhere outside of the subcase manager that the scale factors are not 1.0. 

 

I actually looked for a possible solution by listing out a solution. It turns out that we don't support listing out a solution either. We do support listing out an entire simulation via Simulation Summary, but it misses this information. You have an enhancement request here.

 

Regards,

Mark

Mark,

thank you for answering.  - But, I'm not sure what you mean exactly.

Does it mean that the enhancement request has reached the development crew now, as you read it? - I assume you are part of the developing team, right? Or does it mean that the problem is worth creating an enhancement request and that is then my part?

 

Best wishes, Michael

Michael,

 

The problem is worth creating an enhancement request by you. There is nothing in the product currently that addresses this. Product management hasn't included anything for this in their plans either.

 

Until 6 months ago I was in CAE product management. I moved to CAE business development, so I'm more external facing now, and not plugged into the development or planning process nearly as much as I was previously.

Mark

OK, I've forced a creation of Enhancement Request at the support page of our supplier. Let's see, what happens, Best wishes, Michael

Info: The enhancement request is placed at GTAC with help of our support provider.

 

IR 9472163 NX10 - Enhancement Request

"If being used Subcase Manager should be more clearly indicated/shown"

 

For myself, I can't visit the enhancement request personally but I hope it's correct. Best wishes, Michael

Michael,

 

I reviewed the enhancement request and it all makes good sense to me. Thanks for submitting it.
