Umberto Iemma posted a comment on discussion Open Discussion
We appreciate your effort, and the fact that you make it available. The problem that I see is that the acousto project is an academic project that follows a strict and rigorous scientific approach in implementing an original BIE formulation. Even if the current released version is limited to static acoustics, it is part of a much more complex code developed throughout the last three decades. The formulation used in acousto is not standard and presents a number of peculiarities in many aspects of...

Hi honestguvnor. The project is still active, even if the current distribution is pretty old. The development is now followed by Lorenzo Burghignoli e Giorgio Palma, two of my collaborators. They have developed a newer version with major improvements of the formulation, including new regularization techniques and the possibility to include moving sources and scatterers. I don't know when they plan to release the new version. BTW, the code compiles and runs well also against current version of libraries,...

Dear Max thank you for your contribution! We are about to release v2.5 and we will test your script also with it. This will be the last Acousto version, then something new will happen .... Thank you again
-
OK, thank you. Before going on I just want to be sure that you are not, in fact, misled by a typo before Eq. 2.6. The line before should read "Substituting into Eq. 2.3 and comparing with 2.4". Clearer now ?

Dear Anton, thank you for interest in Acousto. The approach used in the user manual (Section 4.2.3) and in the Tutorials Book (Section 2.5) differ on the physical meaning of the unknown function. In the Useer Manual is the velocity potential, whereas for the impedent sphere tutorial is the pressure. Which approach are you using ? Umberto

" acousto distribution path” is where you have saved the acoustic distribution on your disk ;-) For example, in my case is “/home/umberto/Software/" U Prof. Umberto IEMMA, PhD Professor of Aerospace Structures and Design Dip. di Ingegneria - Universita' Roma Tre via Vito Volterra 62, 00146 Roma tel. +39-0657333274 fax +39-065593732 http://acousto.sourceforge.net On 26 Feb 2020, at 19:42, Fred Voisin graougraou@users.sourceforge.net<mailto:graougraou@users.sourceforge.net> wrote: Some files (data)...

Alberto, try with "locate libconfig" It returns all the occurences of "libconfig" in file names for your system. Anyway, if you are not an experienced Linux user you should better use the acousto dockerfile. Installation is super easy and the performance is almost the same as for native compilation. U
-
Hi Alberto, it should be somethings with your environment setup. Please use the --with-libconfig option. U

I've tried on a Centos 7.4 VM and works perfectly ! Just install openmpi3 suite and lapack devel package from standard centos repository. Then follow these steps 1) Download latest epel-release rpm from http://download-ib01.fedoraproject.org/pub/epel/7/x86_64/ 2) Install epel-release rpm: # rpm -Uvh epel-release*rpm 3) Install scalapack-openmpi3-static rpm package: # yum install scalapack-openmpi3-static Then, configure acousto with ./configure --enable-mppinew --enable-scalapack_new Now you can...

mmmh, strange... Later this afternoon I'll try to reproduce your probloem here. Now I have to teach ...

please try with the mpi new and sclapack new oprtions

My group is working on a major update that will take some time to be released. Soon, we will publish minor updates to guarantee compatibility with the latest MPI release and fix some installation problem. It seems that there is something wrong in your installation. blas seems to be not present MPI seems to be compiled without fortyran support Check carefully your setup and send a feedback U

Hi James, if you are trying to compile outside a docker cintainer it's not the same issue. CrocoDuck problem was a purely dockerfile problem. Could you please post the config.log ? U
-
Hi CrocoDuck, try the following in the dockerfile change "FROM debian" to "FROM debian:8.6" from the directory where the dockerfile is, issue the command docker build -t name-of-image . -f ./acousto-2.0_dockerfile Let me know ... Umb

Hi CrocoDuck, I'll check the procedure this afternoon and let you know. Best wishes Umb

Hi Thomas, could you please post the log file? U

\omega is measured in rad/sec, not Hz. 2pi325*1.21/103.76=23.813 325*1.21/103.76=3.8 ;-)
-
Actually you don't need to change the name in the configure files. One of the configuration options allows you to provide special names for the libraries. Anyway, thanks for posting your experience.
