present: Steve, Roland, Lucas, Allen, Cheng-Hsin, Liwei

hybrid evolution methods and RK4Prol methods ============================================

* Lucas has tried the RKAB method but finds that time level support in CarpetX does not easily support these, shelved for now * Lucas is now comparing his standalone method with Liwei's and finds that, assuming identical initial data, one gets the same results * now testing implementations with high frequency noise (stability test, Neuman analysis)

CapyrX ======

* Lucas can now evolve Gaussian and standing wave in fully first order formulation with all FD operations successfully (no more shearing effects) * expansion of pulse into curvilinear grid shows no artifacts at interpatch * sees some issues in Cartesian grid, might be boundary conditions not quite right * issue was either projection of or jac derivatives * has tried to run on CPU gut is encountering issues, postpone until Erik can make it

tabulated EOS =============

* Allen is working on tabulated EOS and is looking for a TOV reader that can use LORENE formatted EOS tables * no proposal were made during the call

NewRadX =======

* Liwei updated pull request to main * added a test case that shows the failing behaviour in TestNewRadX * Lucas has reviewed CarpetX pull request, has some minor comments

ReadinterpolateX ================

* Liwei is continuing porting Lorenzo's version to CarpetX

Subcycling in time ==================

* Liwei is continuing to debug BBH simulation on main branch, looking for memory leaks

Derivs thorn ============

* Liwei added higher derivative operators

Yours, Roland
