Hi all, I’ve been trying to run Spritz using initial data generated by the latest version of FUKA for a BNS simulation, but I’ve run into issues related to the Kadath libraries.
At first, I was getting a mismatch error (Assertion ndim==nbr_points.get_ndim()), which suggests an incompatibility between Spritz’s bundled Kadath and the external version of FUKA/Kadath I used to generate the initial data. To fix this, I tried to build Spritz against my own external Kadath installation (~/fuka/lib/libkadath.a) instead of the one bundled in the Einstein Toolkit. I did this by disabling these thorns in my thornlist: Fuka/kadath_pizza, Fuka/KadathImporter and Fuka/KadathThorn. I also added the following lines to my ET_2024_05/Cactus/simfactory/mdb/optionlists/<machine>.cfg KADATH_DIR = $(HOME)/fuka KADATH_INC_DIRS = $(KADATH_DIR)/include KADATH_LIB_DIRS = $(KADATH_DIR)/lib One question so far: Did I do things correctly? Then I removed the old Kadath: rm -rf configs/Spritz_LORENE/build/Kadath The code compiles fine, but when I try to run the executable with my parameter file, using the '-S' option, I get: Error: Thorn kadathimporter not found Error: Thorn kadaththorn not found Activation failed - 2 errors in activation sequence The confusing part is that my ActiveThorns line in the .par file does not explicitly list KadathThorn or KadathImporter: ActiveThorns = "volomnia bnstrackergen bnsanalysis pizzanumutils" Yet Spritz fails because those thorns are missing. From what I understand, some of the thorns I’m using (like volomnia, bnstrackergen, or bnsanalysis) depend on KadathThorn and KadathImporter, so they are indirectly required. The core problem: - I need to keep KadathThorn and KadathImporter active, since my parameter file requires them through dependencies. - But I also need them to link against my external Kadath ( ~/fuka/lib/libkadath.a) so that the FUKA initial data is compatible. Would you have suggestions on the cleanest way to make the ET KadathThorn and KadathImporter use my external Kadath library? Is there a recommended workflow for this? Thanks in advance for your help!
