Partial dforce without resetting

Good day!
Is it possible to re-simulate on a certain tissue area without resetting the existing result? I am happy with the result of the simulation except for one area, but when I try to resimulate it separately, the state of the fabric is reset completely across the entire clothing.

Well, I cheat a little - I would make a morph, then dial in the morph and run the simulation from that stage.

Isn't the morph reset during the simulation?
No.
I use the timeline for simulation. So while it appears to reset, by the time it gets back to the pose, the morph is there too.

How do you make the morph of dforce?
Okay. I use Hexagon, be sure the bridge option in D/S is for the Advanced bridge. {edit > preferences ...}
I run the simulation. Then using the scene tab I select the simulated garment and send it over the bridge to Hexagon. {don't worry, there's nothing to learn about Hexagon required here} In Daz Studio, "clear the simulation" of the garment, keep that garment selected {it's still posed or whatever, that's fine}, In Hexagon select the garment {scene tree on far right side} and then File ... send it back over the bridge to D/S. In making the morph, double click on some areas to change options {i.e. name the morph} and right-click to change other options. REVERSE DEFORMATIONS. After the morph is 'made' - in D/S dial it in to be sure it took all right, then dial out that morph and Save it as a morph asset {as always just select the one morph being made}. Then I remove the garment from the scene and load in a fresh one {to clear any attachments with regards to DForce}, dial in the morph ... then pick the next garment that I'm adding DForce to and run the simulation on that garment. Whether or not I make any more morphs depends upon how likely I am to ever want to remake the scene.
Generally speaking it takes less time to make a morph than it does to run the simulations.

Thanks! I have another question. Before the simulation, the clothes is reset to default. Can I make it so that the clothes are simulated from the current position?
Before each simulation, the clothes are reset to the standard state. Can I simulate clothes without resetting them? For example, I did a 30-frame animation and simulated clothes. But then I decide to continue the animation to 60 frames, but now I have to do the simulation from the first frame. But I would like to just simulate it from 30 to 60 frames. Is this possible?
Technically, yes. I'm not sure on the details but there's a way to "memorize pose" and then the simulation will start from said pose. In my projects I've found things work just fine by letting it simulate from default - I have the pose keyed at 30 on the timeline. Also to notice in the pose actions themselves - scrub along the timeline and be sure that the figure is not clipping itself. For eg. if the legs are crossing through each other, the simulation will try to do that as well {tends to explode then or just look terrible}. However many use the "memorize pose" feature.
The information about the energy and momentum in the mesh is not saved, so you cannot literally resume a simualtion. You could spawn it to a morph and then simulate on from that, but it would not be the same as running the simulation from scratch. You can turn a simualtion into a morph via https://www.daz3d.com/dforce2morph or by OBJ export/morph import.

Oh that looks handy Richard :-) Sure hope they can easily make all the plugins work in D/S5 too.
@ op, have attached a couple of images re: memorizing pose. I think how this works is to pose the figure at the beginning of the Timeline and make a "key" there. Then select the clothing to run the sim on of course.
And all world take note, for once I'm using the up-to-date D/S4.x right away. [instead of waiting a few years lol ...]
Thank you Catherine3678ab! I was having issues with the morph looking wrong when I did the steps through DS (havent been able to pick up dforce2morph yet) This worked perfectly! (I have no knowledge with Hexagon)
Happy to hear that it helped somebody :-)
Yes for many basic "just want to make a morph" all one has to do is throw it back and forth over the bridge. It does all the calculations :-)
Down the road in time, it is in the "UV&Paint" tab that one can use "gently" the smoother, the pincher [I seldom use this, can cause problems] or the inflate tool. Or grab a hold of some dots or lines and move those around. Just for a small amount of morphing though. If one wants to make drastic morph projects one may wish to invest in ZBrush, etc.
