So you will also need to reduce the size of the elements in the <code>kWaveArray</code> so they fit on the grid. </p> http://www.k-wave.org/forum/topic/adjust-spatial-resolution-in-kwavearray#post-8318 Mon, 27 Sep 2021 02:57:22 +0000 zengqw2021 8318@http://www.k-wave.org/forum/ <p>Hi,<br /> In ex02_simple_example_kWaveArray_sensor.m, I have reset "dx=0.5e-5;dy=0.5e-5". A problem occurred:<br /> Error in kspaceFirstOrder_inputChecking (line 616)<br /> [sensor.mask, order_index, reorder_index] = cart2grid(kgrid, sensor.mask, flags.axisymmetric);</p> <p>Error in kspaceFirstOrder2D (line 537)<br /> kspaceFirstOrder_inputChecking;</p> <p>Error in ex02_simple_example_kWaveArray_sensor (line 82)<br /> sensor_data_point = kspaceFirstOrder2D(kgrid, medium, source, sensor);</p> <p>How to fix this problem </p>
