Hello! I want to map the results of a uniform grid onto a locally encrypted grid, but the following problem always arises when I map.So I want to ask how to correctly map from a uniform mesh to a locally dense mesh?

Source time: 24000
Target time: 24000

Create meshes

Source mesh size: 431200 Target mesh size: 1368752


Consistently creating and mapping fields for time 24000

Creating mesh-to-mesh addressing for region0 and region0 regions using direct
Overlap volume: 4.93144e+09
Creating AMI between source patch lower and target patch lower using directAMI
AMI: Creating addressing and weights between 9800 source faces and 30656 target faces
AMI: 1236 non-overlap faces identified
AMI: Patch source sum(weights) min/max/average = 1, 1, 1
AMI: Patch target sum(weights) min/max/average = 1, 1, 1
Creating AMI between source patch upper and target patch upper using directAMI
AMI: Creating addressing and weights between 9800 source faces and 9800 target faces
AMI: Patch source sum(weights) min/max/average = 1, 1, 1
AMI: Patch target sum(weights) min/max/average = 1, 1, 1
interpolating T

The computational domain and boundary conditions of my two sets of meshes are the same: dx=23 for uniform meshes and dx=23-11.5-5.75 for local encrypted meshes. The encrypted region is located in the center of the computational domain. The command I used and the mapFields file looks like this:
