Hallo Kevin, when I figured out, how to compile the acousto program files, then I found two essential issues: the first was to link to the right lapack library; best solution was: ln -s /usr/lib/x86_64-linux-gnu/libscalapack-openmpi.a /usr/lib/x86_64-linux-gnu/libscalapack.a or alternatively, if your distribution has a dynamic library (check the respective file for existence): ln -s /usr/lib/x86_64-linux-gnu/libscalapack-openmpi.so /usr/lib/x86_64-linux-gnu/libscalapack.so the second issue was: The...

Hallo Giorgio, many thanks for your investigation and your reply :-) It's valuable to see that custombc 2 does no more than writing the boundcond file and then performing the same as custombc 1 I have now created the boundcond with a simple script file; perhaps it could be attached to the RoomAcoustics tutorial; I attach it below... As a feedback, I wanted to say, that at the moment I prefer custombc=0 because in a simple calculation I need just a frequency-independent absorption coefficient, which...
-
Hallo Acousto team, Giorgio, I investigated further custom boundcond 2 and everything is fine when the number of frequencies nome =... equals the number of boundary conditions, e.g. gmshbc=["wall%d",...]; nome=3; ... wall0={...}; wall1={...}; wall2={...}; ... or gmshbc=["wall",...]; nome=1; ... wall={...}; ... However, if nome is greater than the number of given conditions, even with frequency independent conditions gmshbc=["wall","ceil", "floor"]; nome=3; ... wall={...}; ceil={...}; floor={...};...
-
Thanks for the info.

-
To put it short; I like very much this feature: boundary condition with gmsh and physical tags, and on the other side I would like to use the impedance boundcond - is it possible to combine these?
-
I didn't investigate it already, but from the definition of the general boundary condition (6.12) in the users guide, I have to provide gamma, lambda and f. However, if I have to provide a constant boundcond for the frequency response, I would prefer to give a constant absorption alpha (not a constant gamma); so the question would be then, could I provide impedance, lambda and f - is that implemented for the boundcond 2?
-
Hallo Giorgio, thank you for the reply and the help That was it, I didn't see that the definition of the custombc had to be outside the modsol structure.... Now it calculates well :-))
-
In the boundary condition I have two frequencies... There is also the question, if I would calculate e.g. a frequency response, does the program make an interpolation for the frequency dependent boundary condition?

Hallo Giorgio, thank you, that's a great offer :-) I include the project files below...

Hello Umberto Iemma, many thanks for your program... I tried to convert the tutorial: Room_Acoustics to the new boundary conditions custombc=2 with the physical tags of the gmsh file. But now I get an error message: 2021-04-29 15:33:56 DEBUG [1/1] modsolinfo->custombc=2 2021-04-29 15:33:56 DEBUG [1/1] Allocating 24 for sizeof(struct phystag)*config_setting_length(phystagcont) 2021-04-29 15:33:56 INFO [1/1] n physical tags = 3 2021-04-29 15:33:56 DEBUG [1/1] reading physical tag [floor] 2021-04-29...

Finally, I did some code cleaning and better commenting in my script. The function is not changed. Best regards

Happy, that I could contribute. And looking forward to your new version :-)

Hallo, I wanted to finish this investigation about Ubuntu installation; meanwhile I did it better... The "BLACS" not found message in newer library versions can mean, that "libscalapack.a" is not found. Because "blacs" is now contained in "scalapack". However, it is not necessary to rebuild scalapack. Instead, the shared libraries in the package "libscalapack-openmpi-dev" are sufficient. However, a link is needed: ln -s /usr/lib/x86_64-linux-gnu/libscalapack-openmpi.so /usr/lib/x86_64-linux-gnu/libscalapack.so...

Tried out Ubuntu 18.04 and current Debian (10.6) shell and the install script (see previous post) worked fine :-)

Here my install script again, tested with a complete vanilla Ubuntu 20.04 and two bugs fixed.

Compile and install ScaLAPACK 2.1.0 from sources (with cmake and default configuration: cp SLmake.inc.example SLmake.inc this gives libscalapack.a in /usr/local/lib For AcouSTO, run ./configure with following options (of course, all necessary libraries must be installed): ./configure --prefix=/usr/local \ --enable-mpinew --enable-scalapack_new \ --with-libconfig=/usr/lib/x86_64-linux-gnu \ --with-blas=/usr/lib/x86_64-linux-gnu/blas...

Hello, I have the same problem: blacs not working in current Ubuntu 20.04 However, I found that in Ubuntu 16.04 there was libblacs-openmpi-dev Now, in Ubuntu 20.04, there is only a "virtual" package, "provided" by libscalapack-openmpi-dev [...] By the way, the other installation option in docker, with the modification FROM debian:8.6 as described above by Umberto lemma was also successful for me.
