Hello,
I have come across an issue while using DART with Gazebo in which the Dantzig LCP solver returns nans, causing the simulation to fail. I am using the Gazebo default branch and DART master bran…

It seems if domain is S.Reals, intermediat…

We currently implement a 3D space charge solver, but for many cases a 2D (transverse) solver would be sufficient.
There are two options we are interested in, for different science cases:

Hi all,
in the near future I will work a lot with PKPD models, mainly in the context of coupling cellular/tissue/organ models with whole-body models. A first review of existing models showed that mo…

The db48x needs the emissive power Black-Body Integral function F0λ(T_K, λ_nm) defined in the HP50G (HP50G_AUR 3-82 and 5-31 for a graphic illustration of the under the curve surface). This is a low p…

Hello,
I would like to know what kind of `noise_type` one should pick for a homogeneous SDE:
$$dX(t) = A(t)X(t) + \sum_{j=1}^m B_j(t)X(t) dW_j(t),$$
where $A(t)$ and $B_j(t)$ are square matrices an…

In step-62 a frequency sweep is done to calculate the spectrum of an elastic structure.
The mass and stiffness matrices are the same for all the frequency steps. We store them
in the `Quadrature…

I've put together a short list of information I believe could be added to the current PyRK documentation to make things easier for future users, as well as explain more of PyRKs features.

Not sure if this is a known issue, but right now calling `jacobian_ad_forward` with a semidiscretization build from `VolumeIntegralShockCapturingHG` with shock indicator [`IndicatorHennemannGassner`](…

This issue serves as a reminder for a possible addition to the build system in the form of (optionally) detecting and
linking against the tcmalloc library (google thread aware allocator); as such it…
