Hello Pachyderm Users,
We are going through an exciting period, including the startup of an organization to support the growth of Pachyderm, and extend the educational agenda of the project. In the next few weeks, we will be submitting our long-form 501(c)3 application, which will give us the rights of a not-for-profit organization established in the state of Connecticut. As part of the transition, we are phasing out the old website. The new site will be up in the next few weeks, and you can find it at:
 
 
We are looking forward to the next phase of this project, and we hope that you will be there with us to learn and continue to support us!
 
kind regards,

overly long simulation

Hi!I'm running a simulation with a simple model of a room of about 303 cu. m. (5,6x4,3x12,6), so not very big, but it takes almost 20h per source to complete.At the beginning I thought it was due to…Continue

Hi Arthur thanks for your great plugin and hi everyone,

on "pachyderm hybrid models" window

-I am facing some problems on opening analysis data that was previously saved as a file type ".pac1" from pachyderm.

-Also, I find a problem at the material section,  when I assign a custom material on a layer, it will automatically reassign this material to all the project layers. So I am using the "object acoustic setting" at rhino properties to input the absorption material data.

I am running latest pachyderm on windows Rhino 6.

I am just wondering if this is something known or is me doing something wrong.

Best regards

Hi Authur

I am study in master degree and i am researching about Changing Acoustic in Multi functional space  

I have some issue about "Ray tracing" Component in grasshopper when i put all the value and then the Ray tracing will show a message "Preparing Threads" for long time and then clash and not responding and another case it can work but just some Ray that reached and then it clash again. I don't know why this component can not run. How solve this problem ? what should i do ?

ps. I use Minimum Convergence so Do i no need to put value in Number of Rays ?

 

Thank you

Hi Prakati,

Simple. Load Pachyderm for rhino before opening grasshopper. The grasshopper plugin depends on the rhino plugin to work.

To load it, just run any Pachyderm command in the command line

Hi Prakrati,

It sounds like your screen is a bit small. sorry about that. I'm afraid I don't have a good solution for you at this time.

Maybe you can find a larger screen somewhere. (I'll see how small I can allow it to get for a future release... I think there was a limit in terms of the legibility of the graphics, though).

hey arthur 

thanks for replying . i have one more doubt how to adjust the interface of the call absorption . i have already tried to adjust the screen resolution it doesn't fit . what to do ? 

thanks

Hi Prakati,

In the latest version, I removed the "Apply" button by popular request. Instead, as soon as you click a library item, it applies it to the selected layer automatically.

For some, that was less confusing.

But is the issue actually that you don't have a library? It's hard to know why without looking at your computer. Most likely, the file is missing. Here is where it would be normally:

C:\Users\[Username]\AppData\Roaming\Pachyderm

In case it is indeed missing, please take mine: Pach_Materials_Library.txt

There isn't a whole lot in there - it is up to the users to fill it. But hopefully this helps.

Arthur
