Hi, everyone. I want to reset all fields like the code shown below. It works well, but can we implement it easier?
@ti.kernel
def clear_data(self):
for i, j in self.values:
self.values[i, j] = 0.
for i, j in self.cases:
self.cases[i, j] = 0
self.edges[i * self.nely + j, 0] = ti.Vector([0., 0.])
self.edges[i * self.nely + j, 1] = ti.Vector([0., 0.])
self.edges[i * self.nely + j, 2] = ti.Vector([0., 0.])
self.edges[i * self.nely + j, 3] = ti.Vector([0., 0.])
I tried to re-declare these field in python scope. The code is shown below. But when I had called this function in a while loop, the GUI window crashed and returned an error. The question is: What is the correct operation to reset a field?
def clear_data(self):
self.values = ti.field(ti.f32, (self.nelx + 1, self.nely + 1))
self.cases = ti.field(ti.i32, (self.nelx, self.nely))
self.edges = ti.Vector.field(2, ti.f32, (self.nelx * self.nely, 4))
