Hi
How do you get around SW not being backwards compatible ?
I mean that you cannot run a 2012 file on 2009
Richard

Hi
WOODY@DDLLC.....Is that Solidworks Flo Simulation that you are using?
If it is which year do you have?
Thanks
Richard

Richard, I use FS 2009 for setup & small jobs and FS 2012 for the big runs. One core w/4MB vs 6 cores w/12MB. Sometimes no substitute for cubic inches!  :cheers:

Richard, model files can be passed backwards as a parasolid. I usually export CFD models to parasolid as it will fix small "leaks" in the model. Geometry has to be watertight for CFD! But flow files and everything else is one way. And many of us complain about this at SolidWorks World every year! 2013 is supposed to be bi-directional but I also hear that may not be true!

Hi
Yes it is a pain...we have guys here that have everything from 2008 through to 2012 and we get caught out often.
But I have been swapping iges file but will try the Parasolids.
I have never had the time to do anything but play with Flo...need to find more time and get into it.

More quality parts in the build diary.

It is exciting to see the workmanship that is going into the current builds.

ROB..... that is excellent.

"Blue" has been at the shop this week. Getting lots done. My brain is getting a little sore from stuffing if full of composite structures knowledge.
Hope everybody has fun at Elmo this weekend!
Pictures of this weeks progress to be added soon.

Can we do this?
In reference to our interior panels, we have one bar (on each side) that protrudes into the interior by about 3/4".
Can we bring our interior panels right up to the bar like shown here or do we need to completely cover the bar?

We got a lot of stuff done this week with Eric here.
We don't have a lot to show pictures of but we worked out several small but not insignificant problems.

Rob,  That is what the tech. committee is for---I had a similar issues: I asked  for a variance on them, several were approved and and a very fair compromise was reached on the other:  One of the compromises entailed gussets--  I will need to use a larger that 4" on a particular joint intersection --but leave a small opening at the juncture open for the "Jaws of Life"!   Very helpful, open discussion!  In my case I took my car to them but I wanted to go to the races anyhow---As I make the changes they will be emailed and their replies will be printed and put in the log book per their instructions-- My suggestion, Send picts now get them involved!

Rob, our streamliner has the .090 panels stitch welded in the middle of the tubes, basically making huge gussets.  So half of the tube is inside the cockpit, never been a question during tech. The rule is that you can't sit on the outer skin... you need a secondary floor and sides in the cockpit that also serves to retain arms and legs inside.  But, as Sparky has suggested, you can never involve the tech chair too early in a build.  I'd put together a little slide show of the build and send it in for review.  It is really looking great and safe... the important part is safe.

+1 on getting Tech involved early, Grumm must be getting sick of my emails but at least we should avoid a WTF moment when I'm finished, hopefully......

Ours is like Stainless's, except heavier, I think it's just under 3/16ths which encloses the cockpit welded along the midline of the tubing, the firewall and seat back are 1/4 as is the floor.We tried to build in as much weight as we could having such little space to play with.If you have the room there are advantages to having them inside as they'd minimise impact points in an upset.Looking at your car I'm thinking you're hoping to run a little lighter than most   :cheers:

Rob, Always great to have the faces of the main perpetrators! Would have liked to have been a mouse in the room! :-D
