Software :: Acoustic Simulation Program Or - Sound Wave Simulation Program
Feb 21, 2010
I am looking for a very particular sound wave simulation program. To get an understanding of what i want let me describe it to you in a different way.
Imagine your look at a bowl of water from above and you poke the water at a specific frequency you will see wave patterns showing. Well im after a program that can generate that pattern with any particular frequency that i set, and to allow me to place different shapes and objects around the sound source or sources (i may want to use more than one sound source that may or may not be at the same frequency as first.) and see what kind of reflections i get.
I was also wondering if instead of a point sound source you could have an entire shape giving off a specific vibration. This will give very interesting results that i am also after.
There are some programs that show sound simulations that i have described but nothing that can do the requirements that i desire. Do any of you guys know of any programs that can do this? if not how much would it cost to build such a program?

I have successfully changed and configured TORA in ns-2.34 (in fedora 9), as learnt from;[URL]..Now, when I run the simulation, it hangs and does not finish. If the simulation time is 20 seconds, it do completes but for simulation times more than 20 seconds, it never comes to an end.
Code:
num_nodes is set 50
INITIALIZE THE LIST xListHead
Loading scenario file...
Loading connection pattern file...
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 550.0
SORTING LISTS ...DONE!
I have tried increasing the bandwidth and interface queue lengths but got no improvement.Please note that the same TCL scripts are running with other protocols like DSDV, AODV etc

I'm doing some simulations (using Iperf) to obtain throughputs values of a link between two gigabit ethernet cards for different delays and different drop probability (using netem) .... Now I have to do a 3minute long simulation in which during the firstnute the bandwidth is 1000Mbit/s, 500Mbit/s during the second minute and 1000Mbit/s during ththird one....Does anybody know how can i do this type simulation

making My simulation graphs in Ns-2.34 in ubuntu how i can make them. my simualtion is about Home automation lighting control and i wnated to make 6 graphs1) time VS Residaul energy ( remaining enregy of the nodes)like sensors (we have mentioned Insteon sensor and Switchlinc Dimmer)use 9V battery in them. the 9V should be converted in joules and Energy on Y-axis should be in Joules and time on X-axis should be of simulation timeThe graph would be showing after running the simulation 3000 times how much energy is remaining or how much energy is consumed in the nodes after sending 2000 packets.2) Packet size Vs Delay, Delay on Y-axis and Packet size on X-axis with there units and the graph would be showing if Pacjet size increases how much delay is created.3) Throughput Vs Badwidth. througput on Y-axis and Bandwidth on X-axis4) Packets Loss Vs data rate5) Packets sent Vs data rate6) Packets received Vs data rate

I am currently using Cent OS 5.4 and I was able to successfully install ns 2.34 on the machine and run a few test FTP simulations. The problem stems from the fact that the ns 2 installation used in the ATM simulation , in the link provided, uses ns2.1b7 or ns2.1b9.
I have tried to see if I could cheat and implement the patch for my ns2.34 installation but that failed flat out ( make failed with an incorrect parameter error) I then tried to download the older versions of ns that were used in the ATM Simulation, ns 2.1b9 and that failed too ( otcl make failed with g++ error) which i figured failed because I am using g++ version 4.1 . ( From the docuemntation, this particular version of the software had trouble with any g++ version > 3.2)
a) Is anyone aware of any ATM Simulation patch for the current version of ns i.e. ns 2.34?
b) Is there anyway I can confgure the patch for the ns2.1b9/7 version to work smoothly with the ns2.34 version I have installed?
c) What are the recommendations for me to install the ATM Simulation provided on the URL above.

I've been doing Finite Element simulations with the Ansys software for several years now, and recently I have been allowed to use a cluster running on Linux (it's a Sun Grid Engine, or SGE). Since I am quite newbie to this thing, I have read a lot on the internet to get more familiar with the Unix language. I found some example codes which are supposed to launch Ansys and read input files, but it does not work for me. Actually, what I want to do is simple:
1- I need to use Ansys 12.1 in batch mode, with the Academic Research license (which is called "aa_r");
2- The software should then read my input file (which is an APDL command file (in case you are familiar with it..)) and save the database and results in my working directory on the server.
The software is located in the following path:
/ansys_inc/v121/ansys/bin/ansys121
My working directory:
/home/myusername/
From what I've found on the web, I have to write a shell script that calls the software and specifies the details (batch mode, license name, input file, ...). Then I have to call this script by using the command "qsub".
Script: myjob.sh
Code:
#!/bin/bash
nohup /ansys_inc/v121/ansys/bin/ansys121 -b nolist -p aa_r -j jobname -i jobname.inp -o jobname.out 2>&1 &

Cognitive Radio patch worked with ns-2.31 but when I tried it for ns-2.34 it did not work. Is there a separate patch available for ns-2.34 to support cognitive radio ? Or does it not work with ns-2.34 at all ?

I want to change parameters of a RED queue during the simulation but it seems that some parameters can be modified only before starting the simulation, not dynamically, while the simulation is in progress. For example the following subroutines works before $ns run command but it do not change the behavior of the queue during the simulation( I want to change maxthresh_ and thresh_ after $ns
run command): Code: proc setREDParameters { redQueue MINth MAXth PER_MaxP Wq } {
$redQueue set thresh_ $MINth
$redQueue set maxthresh_ $MAXth
[code]....

I was wondering whether there is an inbuilt logging system in UNIX?
I ran and installation and the program opened up automatically but I can't find the program executable.
If I could find a log then I could locate this file.

Is there anything like burning rom from nero or roxio cd/dvd copier. Do you know of any dvd copying program? like without making the image and then burning with just one process just copy the disc sorta program like roxio dvd copier? I wanted to make copies of movies I made a dvd of but aside from image burn which is a hassle to make the image first. is there something for burning on the fly or dvd/cd copying? infrarecorder and cdburnerxp do not work for me at all.

Anyone here have a good solution for individually controlling sound output without relying on that individual programs audio settings? For example:I am writing a paper while listening to some nice creative commons jamendo music, and I have to look something up online - I don't want to hear random audio/video advertisements.
or I get a VoIP call and I want that program to continue with sound, but want to mute my 8bit sequencer and whatever else.
