Pls help. Proper way to continue simulation?

Hi, 

So, I need to continue simulation after what I left of. 
I generated last 5 sim files using explicit cache.

 

I was following Alessandro's tutorial. It worked on test, but not in real sim. 

Also I tried setting last working sim file as initial cache, failed too.

 

What is the proper way, fool proof method of doing this?

 

This is what I did

 

1. explicit cache last 5 frame named explicitcache.$SF.sim. Say, I got 100-105

2. delete last sim file (105).

3. reopen houdini. open scene

4. Reset Simulation on AutoDopNetwork

5. left start frame as 1 on AutoDopNetwork

6. set dop import rop to 100, hit render

    or set dop import rop tp 105, hit render

    or set cop import top to 106, hit render

 

all failed. It cook for a while on frame 106 then swoosh to last frame in few second. The bgeo file came out 500kb instead of 3GB, as it should.

 

I've been using H for a year and never get this thing right :(

Delete all the explicit cache frames except last one which you want to set initial state to. Or rather than doing this manually, you can use "Explicit Frame To Keep" parameter.

Nothing else you need to do. It'll work fine.

So I continue on the last successful explicit cache frame or the frame after it?

I mean on the dop import I/O.

You need not to change anything from default settings. When you feed last frame in initial state parameter, it automatically understand from where to continue.  

Just continue whatever is your first frame on dopnetwork.
