Hi, @lululxvi, when I try to train the example [Inverse problem for the fractional Poisson equation in 1D](https://github.com/lululxvi/deepxde/blob/master/examples/pinn_inverse/fractional_Poisson_1d_i…

This CFDPython lessons is the best leasons I 've ever token about CFD. I follow every step until step11. But I got stuck in equation 4 of step11 :
∂2p/∂x2+∂2p/∂y2=−ρ(∂u/∂x*∂u/∂x+2∂u/∂y*∂v/∂x+∂v/∂y*…

Hi all,
it would be a great enhancement to be able to draw random numbers from common distributions inside equations. This would for example allow to implement synaptic release noise by drawing the…

Plan to add basic particle support:
- Follow implementation used in PeleC (https://github.com/AMReX-Combustion/PeleC/blob/development/Source/Particle.cpp)
- This requires both *virtual particles* …

I am trying to understand how two examples (https://github.com/LLNL/echemfem/blob/main/examples/catalyst_layer_Cu.py and https://github.com/LLNL/echemfem/blob/main/examples/bicarb_Ag_Cu_tandem_example…

Hi, I am trying to implement the Laplace equation in 2D as follows:
d2f/dx2 + d2f/dy2 = 0,
with Dirichlet boundary conditions:
f(x,1.0) = -1.0,
f(0.0,y) = f(1.0,y) = f(x,0.0) = 0.0.
Using the …

RLM assumes in general a symmetric distribution otherwise we need to add a term into the estimating equations for Fisher consistency. For the latter case we (will) have special models for specific asy…

Hello,
I'm working with the dynamic pressure perturbation equation (Laplacian of p = -roh*((dudx)**2+(dvdy)**2+(dwdz)**2)). At small scales, what boundary conditions, mxLoop, and tolerance would you …

Looking at the tutorials, the ordering looks a bit random. Perhaps we should reorder the tutorials, roughly in order from least to most advanced, to make it easier to understand them? I'd suggest some…

Hello everyone,
I would like to implement modified gravity models following the mu / gamma parametrisation also used e.g. in MGCAMB (http://arxiv.org/abs/1106.4543), where mu modifies the Poisson equa…
