<p>Hi, I loaded Pachyderm into Rino 7 and tried a simple model in a box and it immediately crashed Rhino. I cycled through that a few times with the same result. I off loaded Rhino 7 and re-loaded Pachyderm to no avail. I then purchased Rhino 8 and cycled through the same problem. Now Pachyderm will not even load into either version of Rhino. It will run when installed and act as if it installed but it is not accessible in Rhino nor Grasshopper.</p>

<p>Hello everyone,</p>
<p>I run often in some Problems with the analyisis of the outside space.</p>
<p>It often makes an invisible Space where the soundwaves bounces of from even tho that Space doesnt exist in the Modell.</p>
<p></p>
<p>Could anyone help?</p>
<p>Sorry for the WeTransfer Link but somehow the Modell is to Big</p>

<p>Hi all, </p>
<p>I would like to have 3 sound sources emitting sound simultaneously. </p>
<p>I can input 3 sources, but I could only get measurement from the receiver for each of the sound sources respectively. </p>
<p>Instead, I would like to have one measurement for the three source points. </p>
<p>Does anyone know the way?</p>
<p>Thanks</p>

<p>Hello everyone!</p>
<p>I set the particles to downgrade from red at the beggining (a hot colour) to blue at the end (a cold colour), but when I run the simulation some of the first frames turns from red to a kind of purple and then red again. My deduction is that some of the old particles crash with some new particles and the first colour (red) join with the old one (blue), that's why it happens. I would like to know if that is right or if it is another cause for it.</p>

<p>Hello everyone. I am trying to get the absorption coefficient of an element with the "Call absorption designer" in PachyDerm_Acoustic - Pachyderm Hybrid Models. When I set a Porous material + Solid plate or Perforated material it gives me a result about the absorption level in all frequencies; but when I set just the Solid plate or the Perforated material by itself it gives me no result in the absorption chart.</p>

Good morning all,<br />
<br />
I am currently working on the calculation of the reverberation time of different closed spaces. I have a closed geometry (simplified model of the Hypogeum in Malta), and what I did was change the scale of it, so I had 3 versiones in: 1:1 / 1:2 / 1:5. What caught my attention was that the reverberation time in the 3 cases was quite similar even when the scales were so different and I don’t believe this makes sense at least from a theoretical point of view.

I have a closed geometry (simplified model of the Hypogeum in Malta), and what I did was change the scale of it, so I had 3 versiones in: 1:1 / 1:2 / 1:5. What caught my attention was that the reverberation time in the 3 cases was quite similar even when the scales were so different and I don’t believe this makes sense at least from a theoretical point of view. The longer the distance for the sound waves to travel, the longer the reverberation time should be correct? But the results I am getting don’t show any significant changes. I did 4 tests in each geometry and I believe I might have something wrong in my definition, In my Ray tracing component I set it to make the calculation with " Trace Specified Number of Rays", not with the “Minimum Convergence”, since it would take much longer time for computing. I AM BASICALLY TRYING TO UNDERSTAND THE RELATION BETWEEN THE SCALE OF THE INTERIOR SPACE AND THE REVERBERATION TIME. If anyone could take a look I would truly appreciate it since I have no idea what I am doing wrong...Thank you all!<br />

I want to see what's going on in it. <br/> <br/> The Pachyderm case is pretty much a boilerplate tutorial thing, largely copied from Gediminas Kirdeikis's excellent videos.<br/>: <a href="https://www.youtube.com/watch?v=t9t5jnw6XTk">https://www.youtube.com/watch?v=t9t5jnw6XTk</a><br/> <br/> I made truncated copy of the speaker cone, and divided it, evaluating the surface and creating vectors and normals to run the simulation. The surface is offset the speaker cone so that there's nothing co-planar.<br/> <br/> It does solve, but it works with only about 100 sound sources. I wish I could see the wavefront a little better. Increasing the bounces makes it go wrong, as well, with the following error.<br/> "1. Solution exception:Index was outside the bounds of the array."<br/> <br/> Also, I tried adjusting the voxel grid depth. Set to on zero, it doesn't run. Other values don't seem to help the problem.<br/> <br/> Is there is anything I could set to get more rays or bounces without throwing an exception?<br/> <br/>I've added blurry Cloud objects, and set the gradient transparency, but what other kind of visualization should I be doing for the most fun--err, um most helpful data assessment for further consideration?<br/> <br/> Thank you.<br/> --BrendaEM</p> Chrash for getting the simulation mapping methodtag:www.grasshopper3d.com,2022-10-29:2985220:Topic:22671862022-10-29T23:00:25.154ZAlireza Mohammadihttps://www.grasshopper3d.com/profile/AlirezaMohammadi

<p>Hello to every one.<br/>I am getting a simulation of a residential complex in pachyderm. I need to say that I have tried a lot to model the project clear. because due to I was working with rhino 6 till last week and I have entered the model from sketchup the based model was mesh based so I have model and convert a lot of mesh objects to nubes so lots of time the model did not run for simulatio beacuse it had bad objects in itself until I got success to remove and repair bad objects but now after running the simulation when I want to get the mesh gradient on the surfaces of the simulated project suddenly the rhino crash and close completely. I had this problem for another project once and it was due to the size of meshes but when I got the mesh sizes larger it soved and the software gave the result. but right now how much I change the size of meshes it would not change in results and with each size of mesh resolutions the analysis result would not give me the mesh results and it will crash and close rhino.<br/>I would really thank you if some body can help me to find the problem if is there any problem in the file. But I am really desperate and I don't know where the problem is with the file. And it is possible that the problem is due to the defect and weakness of my system configuration?<br/><br/></p>
