Probem with installation

Hi everyone,I have tried to install Pachyderm on my computer but I'm facing an issue; when I start the installation it tells me that Rhinoceros5 SR12 is required but I only have Rhinoceros5 SR 5 and…Continue

Hi all,

Daniele and I have worked through the issue. It seems to me that this is not terribly clear in the website documentation, so I will say it here. Your model must be in meters for it to work correctly in Pachyderm. Maybe someday I will fix this, but for now, in order to prevent  an onslaught of bugs, please work in meters.

Rhino makes it pretty easy to fix this. I can be a little trickier in Grasshopper, but still not overly complicated.

kind regards,

Arthur

Can you send me your email to send you the project?
Or write it at rizza.d@hotmail.it
Thank you

Kind regards,

Daniele

Hi Danielle,

There are no limits, and your problem seems very different from Stracus's problem. His originated in the Scene class, and most likely had to do with his model. Yours, from your picture, occurs after running a simulation, and has to do with composing the Impulse Response.

I can't tell what is wrong with it from your picture. Please email me your files and I can have a look.

kind regards,

Arthur

Hi Arthur,

Like Stracus, when I launch my analysis, appears an error that says "Index beyond the matrix limits".
Where is it possible change these limits?

Hi,

There is no limit on the number of surfaces which can be handled, but if any of them cannot generate a render mesh, it may crash.

You will have to trouble shoot your model in order to make sure that none of the geometry is bad.

I don't understand your second question. Could you please explain?

Arthur

Hi Arthur,

I am using your software for an acoustic simulation. Everything looks working in the grasshopper system but I have two questions. 

1. How many surfaces can Pachyderm control in Grasshopper? For now my project is not less then 3800 surfaces and everything is crashing when I am setting a polygon scene.

2. The parameter ED is always overload for the matrix. Is there any secret to solve this problem?

Many thanks

Hi Arthur,

is there a way to export analyses from simulations in a spreadsheet-friendly (or otherwise parseable) format?

Arthur, 

I made it through my Thesis project. Thank you for all your help and for creating this tool! You are saving the world...

Hi Arthur,

Do you have any GH acoustics file that I can study to learn to use parametric pachyderm?
Thank you

Daniele

Hi Arthur,
I have the last version of Rhinoceros and Pachyderm so this is not the problem. Maybe my libraries are blocked but I don't know how I can unlock it.
This evening I tried to start the analysis in a simple cubic room and the "calculation solution" started. Maybe my last model was too complicated. It is possibile? 
I'll write you as soon as try to remodel the new room.
Thank you

Daniele
